Introduction
Imaging cells has become an essential technology in many laboratories working in the life sciences. The components needed for such image acquisition consist of a microscope, cameras, light sources, mirrors, filters mounted in motorized filter wheels, x-y-z stages, and shutters. In practice, many complicated sequences of motorized operations are needed to achieve the imaging strategy desired by the researcher (e.g. acquiring images from multiple wavelengths). Thus, computer control of image acquisition is an integral part of contemporary microscopy.
From the user’s standpoint, the whole setup (a microscope equipped with camera, stage, filter wheels, etc.) ideally should appear as an integrated, coherent system – an “appliance.” This appliance should allow for effective and comfortable interactive work, as well as unattended, completely automated operation.
Available commercial packages more or less provide the needed functionality for controlling automated microscopes, but, because they are proprietary and closed, they are difficult to extend and customize. New devices cannot be added to the system unless the software vendor chooses to provide appropriate drivers. Sometimes the cost of configuring the system with all necessary software and drivers can be quite high.
In contrast to virtually all of the available commercial solutions, Micro-Manager supports multiple platforms (Windows, Mac and Linux) and provides an open plugin interface for adding new devices. In addition, Micro-Manager is compatible with the widely used image processing package ImageJ, which is also available in the public domain. Combined with ImageJ, Micro-Manager provides a full-featured microscope management and image processing package, comparable in capabilities to commercial solutions. It is distributed free of charge and under an Open Source license. Its code base and functionality can be customized, extended and re-used with practically no restrictions.
Installation
After you install Micro-Manager according to the instructions for your platform (below), you can test-drive the software in demo-mode. The application will start in demo-mode by default after initial installation. To use Micro-Manager with your microscope, you will need to create a configuration file for the hardware components that are part of your setup.
The configuration process is described in the Configuration Guide. You will need to create a configuration file specific to your system.
Installation on Windows
Run the installer (MM_Setup_x_y_zz.exe) and follow the prompts. The package includes a copy of ImageJ; it may be necessary to install or update Java on your computer. Besides the manufacturer’s low-level drivers for your camera and possibly other equipment, no other software is required to fully use Micro-Manager. Micro-Manager will be installed in C:\Program Files\Micro-Manager-x.y.
There are no particular hardware or software requirements. Micro-Manager works on Window 7 or 10 running as either 32-bit or 64-bit. However, some devices will only work using 32-bit drivers. Micro-Manager has also been reported to work with Windows Vista.
Currently, the Micro-Manager installer is not signed. This can cause issues with Windows not trusting the software. If you see the blue “Windows Protected your PC” dialog, click on “More Info”, which will unveil the “Run Anyway” button. If the “Windows Protected your PC” dialog is red, you have multiple options. You can go to Windows Settings, Update & Security, Windows Security, App & Browser control, Reputation based Protection Settings, switch off “Check apps and files”. Or, you can right click on the installer and select “Unblock”.
Installation on Mac OS X
Double click on the file Micro-Manager1.x.yy.dmg. This will open a drive
called ‘Micro-Manager’. The drive is on the desktop and in every Finder
Window. Open the drive (by double-clicking). In the drive there is a
folder called Micro-Manager1.x. You can install the application by
dragging this folder to your Applications folder, or you can launch the
application by opening the folder and double clicking the ‘ImageJ’ icon
(to run a 32-bit version of Micro-Manager) or by clicking the ImageJ64
icon (to run the 64-bit version).
Mac OS X security policies mandate a couple of extra steps (which may be
different in different versions of the OS). Go to System Preferences
> "Security\&Privacy" Click the lock in the bottom left corner, provide
an administrator password, then start up the ImageJ app. When you go to
“Plugins” in the menu, and see the item “Why are plugins missing?”, you
will need to quit ImageJ and move the ImageJ.app to the desktop, then
move it back. On some Macs you will need to press the command (or ctrl,
or option) key while dragging the app to actually move it rather them
make a shortcut (don’t ask me why, but Macs have become very confusing
machines). If Micro-Manager still does not start, check the Java version
by clicking in the lower part of the ImageJ window. If you see that the
Java version is 1.6, you need to install Java 8. Currently, you can get
this from multiple sources, I like
adoptopenjdk. Download and install the latest
version. If ImageJ still picks Java 6, try copying the jre directory
of the adoptopenjdk installation into the Micro-Manager directory.
On MacOS Catalina 10.15.7, and later, the gatekeeper then complains that nothing is signed by a verified developer. The solution to that involves a very large amount of clicking (you have to click several buttons per device adapter to tell gatekeeper that you really do want to run them…)
There is a better solution: open a terminal and run
sudo xattr -r -d com.apple.quarantine <Path to Micromanager Install>
for me that was
sudo xattr -r -d com.apple.quarantine
/Applications/Micro-Manager-2.0.0-gamma1-20210309
If you already use ImageJ
Micro-Manager is packaged as an ImageJ plug-in and contains a copy of the entire ImageJ application, together with the Java run-time environment. Starting Micro-Manager will automatically start ImageJ as well. If you already use ImageJ and have it installed on your machine, the original installation will not be affected. Micro-Manager installs and uses its own copy of ImageJ. However, if you have any existing ImageJ macros or plugins that you want to use with Micro-Manager, you will have to copy them manually to the appropriate sub-folders within the Micro-Manager folder. Migrating your favorite ImageJ plugins to Micro-Manager installation should not cause any problems.
Memory settings
It is often necessary to adjust memory settings in order to optimize Micro-Manager performance and prevent errors. See the Configuration Guide for guidelines.
Getting started
On startup Micro-Manager displays a splash screen that allows you to choose a particular hardware configuration file. If you click OK without changing anything, the last successfully used configuration file will be loaded. The Demo configuration (software simulator) will appear as default the first time you start the application. This configuration can be used to explore Micro-Manager features, train novice users and as a reference point for troubleshooting.
Configuring Micro-Manager to work with your specific microscope setup is covered in detail in the Configuration Guide. Micro-Manager has made configuration easy with, the Configuration Wizard utility (Tools | Hardware Configuration Wizard), which provides a step-by-step workflow for creating and managing your hardware configuration. We recommend that you try out the Demo configuration to get familiarized with the program. All examples in this guide refer to the Demo configuration.
Figure 1. Startup screen: selection of the configuration file.
You can also choose to skip loading a configuration file (select “none” in the drop-down list) in which case the application starts without any devices attached. At anytime while using Micro-Manager under the Tools menu you have the options to Load, Reload, Switch and Save your Hardware Configuration files.
The Micro-Manager Main Window
Starting Micro-Manager will also start ImageJ (in fact, ImageJ starts up first and runs Micro-Manager as a plugin). Both ImageJ and Micro-Manager have their own menus (on the Mac you will need to click on either window to display the menu in the main menu bar). Unless specified differently, menu commands in this manual will refer to the Micro-Manager menu. The Micro-Manager and ImageJ windows appear differently on different computer systems; examples from multiple systems are used in this manual.
Figure 2. Main Window displaying device controls and image histogram
After the configuration file is loaded, the Main Window displays the current settings and shows the status of selected devices.
Snapping single images
To obtain a single image from the camera, press the “Snap” button. A display window will pop up with the acquired still image. You can use any of the available ImageJ tools to analyze, save or edit the image. In addition, at the bottom of the window there are shortcut buttons to save the image, enter live mode or send images to album.
Figure 3. Display window for Snap and Live mode.
Each time you press the Snap button, the image in the display window will be updated. The Demo camera driver generates a spatial sine wave that shifts each time you snap a new image. The Main Window displays a histogram of the image; any changes to brightness and contrast will be immediate reflected on the display window.
Live image mode
To see a continuously updated, “live” view from the camera, press the “Live” button. The images will be displayed in the “Live” window. Pressing this button again, stops live mode. Settings in the Main Window can be changed during live mode and the effects on images in the “Live” window will be immediate.
Acquiring a series of images
With the “Album” button, you can collect a series of still images (snaps) in an image series window. The first time you click the “Album” button, a new series window will open, with a fresh image obtained from the camera. Every time you click the “Album” button thereafter, a new image will be added to the series. Click the “Save” button to write all images in the series window to disk.
Histogram, Brightness and Contrast
Figure 4. Histogram in Main Window. Brightness and contrast controls are
shown in red and blue. Histogram range adjustment shown in green.
A histogram of the current (display window) image’s pixel intensities is presented in the graph in the lower part of the Main Window. The histogram is automatically updated each time a new image is received. The histogram range can be adjusted, by clicking on the zoom icons or selecting a pixel range from the drop down menu shown in green. Selecting the “Camera Depth” from the drop-down menu will automatically adjust the histogram range to the hardware bit depth of the image. Some statistical information (min, max, mean, stdev) about the image is also provided.
The “Log hist” checkbox will change the y-axis of the histogram to a log scale.The histogram is overlaid with a graph showing the relation between pixel intensities in the image and display of the image on the screen. This graph allows manipulation of brightness, contrast and gamma of the displayed image.
Brightness and contrast
The end-points of this graph (black and white triangles, boxed in blue in Figure 4) set the lower and upper clipping levels (i.e. pixels values lower than the black triangle will appear as black, pixel values higher than the white triangle will appear as white). The steeper this line, the higher the contrast: moving the line to the right will darken the image, while moving it to the left will brighten the image. The “Full” button sets the lower and upper clipping levels to your camera’s full intensity range. The “Auto” button will adjust the lower and upper clipping levels automatically, based on the extreme pixel values in the image. For “Live” imaging you can perform this adjustment continuously by checking the “Auto-stretch” box; once checked you can set a percentage of outliers to ignore.
Gamma Function
The gamma function allows you to change the relation between pixel value in the image and display from linear to hyperbolic. This gamma correction makes it possible to visualize both bright and dark objects in an image simultaneously, which can be beneficial, especially with cameras that have higher dynamic range than the display (for further explanation see the wikipedia article on gamma corrections. The adjustments can be made by clicking and dragging the line just as is shown with the red arrow in figure 4.
Displayed vs. Original Image
Since the original image is saved separately from the displayed image, any adjustments made will apply only to the displayed image - the original image with the actual pixel values will not be affected. Also, because Micro-Manager displays images received from the camera in a standard image window, any ImageJ command can be used to adjust the appearance of the image, including the standard ImageJ Brightness and Contrast dialog.
Refresh
The Micro-Manager main panel will not necessarily be updated when a setting in your microscope changes. This behavior saves resources and avoids continuous polling of the hardware. To bring Micro-Manager in sync with the current state of the hardware, use the ‘Refresh’ button.
Region of Interest (ROI)
Most of the cameras used for microscopy can be configured to image only a Region of Interest (ROI) instead of the full frame. To select an ROI use the rectangle tool (from the ImageJ window) on the image window. By pressing the “ROI” button while the selection is active, you will apply the current rectangle to the camera. If there is no rectangle placed, then pressing the “ROI” button will halve both X and Y dimensions while keeping the same center. Some cameras will internally adjust the rectangle dimensions slightly to fit within specific hardware constraints. To return to the full frame imaging, press the “Full” button (right next to the ROI button).
Zoom
The “Zoom” buttons apply a software zoom to the topmost image window. Software zoom here implies zooming in on the captured image.
Line profile
The “Profile” button opens up a live line profile window. Unlike the regular ImageJ “profile” utility, this window will update each time a new image is displayed in the Live window. The profile is computed from the currently active line drawn over the image. To draw a line, use the standard line tool from the ImageJ toolbar.
Figure 5. Line Profile window.
Camera Settings
A few camera settings found in all systems are directly accessible from the main window:
- Exposure Time: You can set the exposure time of your camera.
- Binning: Apply binning (‘pooling’ of pixels in both x and y direction).
- Active Shutter: You can change the ‘active shutter’: that is, the shutter that Micro-Manager will open before taking an image and close once the image is made.
- Deactivating Auto Shutter: This behavior of automatically opening and closing the shutter can be defeated by unchecking the ‘Auto shutter’ checkbox. Doing so will let you open and close the active shutter with the ‘Open/Close’ button in the Main Window.
Controlling devices
Exploring devices: Device/Property Browser
The Main Window provides control of only a small subset of the device properties loaded in the system. To view and control all devices and all settings available in the currently loaded hardware configuration, use the “Device/Property Browser” (available under the Tools menu). The Device/Property Browser displays a list of all devices and associated “properties” (settings available for each device). Since this list will often be overwhelmingly long, you can restrict the list of displayed devices using the checkboxes in the top left corner of the window. You can inspect and change any setting on any device. Read-only properties are shown as a line with a dark background. To change a setting, change it in the ‘Value’ column and then leave the field using the ‘tab’ key or by clicking the mouse elsewhere in the window.
Figure 6. Device/Property Browser window.
Grouping device properties: Configuration Presets
Obviously, changing individual properties using the Device/Property Browser quickly becomes cumbersome. Micro-Manager therefore provides a way to generate ‘shortcuts’ that let you quickly set groups of device properties. Setting up these Configuration Presets is an important part of configuring Micro-Manager and is described in the Configuration Guide. Placing the cursor over the current preset will display a tool-tip window and show which devices will be affected by the command. In the example in the configuration guide, choosing the “DAPI” channel preset command will move three filter wheels to the appropriate positions.
Figure 7. Detail of the main control window: configuration preset.
There is no limit to the number of devices or number of different properties you can include in one configuration group. You can set objectives, filters, stage positions, camera parameters in a single configuration command. The Configuration Presets shown here are just an example (used in the demo configuration). In some cases, device properties can show up as a slider, making it easy to set things like camera gain or temperature.
Recording Images
Multi-dimensional acquisition
To acquire multi-image stacks, press the “Multi-D Acq.” button to open
the Acquisition Control dialog (this dialog can also be reached through
the ’’’ Tools | Acquisition ‘’’ menu entry). Micro-Manager
allows you to create a stack as multi-channel (wavelength coordinate),
multi-frame (time coordinate), multi-slice (Z coordinate),
multi-position (XY coordinate), or any combination of these.
Figure 8. Acquisition control dialog.
After defining channels, slices and frames by using controls in the dialog, press the “Acquire” button. The acquisition starts immediately and an Image Viewer window will open displaying the progress. During and after acquisition you can use controls at the bottom of the 5D-Image window to play-back the sequence, browse channels, slices, frames, or positions, or save the entire image stack to disk.
Time points will allow you to define the number of frames you would like to acquire and the duration of the interval time between each frame. If you would like to acquire a continuous acquisition then simple specify the interval time as “0”. The rate at which you acquire images will then be limited only by the speed at which your camera will acquire an image (hardware specific) and the exposure time you specify in the Main Window. For more complex time lapse setup click on the ‘Advanced’ button in the acquisition control dialogue.
Z Slices can be set either as relative to the current position (you will need to type in the start and end position) or as absolute positions. If absolute positions are selected, the ‘Set’ buttons will become active. Clicking these will set the current position to start or end.
Channels can be selected from the active ‘Channel group’. Channel groups are the Configuration Preset groups that are defined in the configuration settings section in Micro-Manager’s Main Window. You will need to set the desired exposure time for each channel. You can also set a z-offset for each channel, which can be useful when the main object in one of the channels is in a different focal plane from the other channels. Setting ‘Skip Frame’ to a number other than 0 will cause the acquisition to ‘skip’ taking an image in that channel (after taking the first image) for the indicated number of frames. The 5D-Image Viewer will ‘fill in’ these skipped frames with the previous image. In some situations it may be desirable to acquire certain channels at lower sampling rates, to reduce photo-toxicity and to save disk space. Clicking inside the ‘Color’ column will open up a Color selector that lets you select the color to be used for that channel in the 5D-Image Viewer. (You can also change colors later on in the Image Viewer.)
Acquisition Order lets you choose between carrying out z-stacks with each channel (Slices first) or switching channels at each z-position (Channels first). ‘Time first’ mode will take a complete sequences of frames at a single position before moving on to the next, whereas ‘Positions first’ mode will cycle between all position at each time point, in effect acquiring time lapse sequences at all positions.
Checking the Use XY list option will cause the acquisition to be executed at each position defined in the Position List. Autofocus options are described below. If the Save images option is selected, images will be saved to disk continuously during the acquisition. If this option is not selected, images are accumulated only in the 5D-Image window, and once the acquisition is finished, image data can be saved to disk. However, saving files automatically during acquisition secures the acquired data against an unexpected computer failure or accidental closing of image window.
Fast Time Series Acquisition (Burst)
If you would like to acquire ‘bursts’ of images as fast as possible, Micro-Manager’s Multi-dimensional Acquisition engine is designed to intelligently take care of this. You will need to:
- Set the time interval between frames to zero
- Deactivate Z Stacks
- Choose Time First
- Use no channels or a single chnanel
Thus you will have removed any delay that would get in the way of the fast acquisition. In previous Micro-Manager versions this was known as Burst Mode.
Split View
Split View functionality (compatible with such devices as the DualView or OptoSplit) is now available as a plugin.
Autofocus
Micro-Manager has a single, integrated user interface for hardware- and software-based autofocus. In the main window, press the Set autofocus options button (wrench icon) to open the Autofocus Properties dialog box. Here you can choose which autofocus mechanism to use among available hardware- and software-based options. You can then edit the settings for your chosen autofocus mechanism. The Duo autofocus option allows you to combine two autofocus mechanisms, so that they operate sequentially, one after the other.
The Autofocus Now button (icon with binoculars) on the Main Window will cause the autofocus mechanism you have chosen to execute its focusing protocol once.
Hardware Autofocus
Hardware-based autofocus support is provided for the Nikon Perfect Focus (PFS), ASI CRIFF and CRISP, Zeiss Definite Focus, and Olympus Z Drift Correction (ZDC) devices. These devices bounce an infrared reference beam off a surface of the coverslip, and use this reflection to adjust the focal position. To activate one of these devices in Micro-Manager, you need to include it in the Hardware Configuration and select it in the Autofocus Properties dialog.
Software Autofocus
Software-based autofocus plugins are also available in the Autofocus Properties dialog. They should work with any camera and Z-stage. These autofocus plugins iteratively adjust the focal position and acquire images to optimize a specific image feature. For example, Pakpoom Subsoontorn & Hernan Garcia (Caltech) contributed a Java plugin module (“JAF H&P”) for auto-focusing based on the relative strength of gradients in the image (edge ‘sharpness’). See here for further documentation of this autofocus plugin.
Autofocus in Multi-D Acquisition
The Multi-Dimensional Acquisition window offers integration with the autofocus system. Check the checkbox in the Autofocus section to activate autofocus during the multi-dimensional acquisition. The Options button (wrench icon) in the Autofocus section allows you to choose the autofocus mechanism and configure it. You can also specify how many frames (time points) will be skipped between autofocus events. If you have a hardware autofocus, it will be activated just before image acquisition and then be switched off again. If you rather have the hardware autofocus switched on continuously, do not check the autofocus checkbox, but be sure that the hardware autofocus is switched on before you start the acquisition.
Positioning
Position List Dialog
The Position List dialog can be reached from the menu (Tools | XY List), and from the Multi-dimensional Acquisition window (button next to ‘Use XY list’). The Position List is used to record the positions of stages in your system. At the bottom of the dialog is a list of available stage axes, any of which you can select to use for recording positions.
Figure 10. Position List dialog.
Use the Mark button to record the current stage position for all stages you have selected to use. When a position is selected the button will be named Replace and pressing the button will overwrite the selected position. Positions can be de-selected by clicking on them.
You can revisit a site by selecting the position and pressing the Go to button. The Refresh button will update the stage positions shown in the Current position pane. You can change the name of each position.
Position lists can be saved (Save As button) and re-used later (Load). When saving and re-using position lists, you should make sure that the coordinate systems of your stages are reproducible between invocations of the program, possibly using the Set Origin button. This will drive all stages to their origin and set this as the base of their coordinate system. Be extremely careful when doing so, since it is possible to run your XY stage into one of your expensive objective lenses!
Tile Creator
The Create Grid button in the Position List Dialog will open the Tile Creator Dialog. The purpose of this dialog is to quickly create a position list covering the area of an object (larger than a single image) in the microscope specimen.
Figure 11. Tile Creator dialog.
Method 1: Use the Set buttons of the Tile Creator Dialog to mark at least two of the corners of the object that you are interested in. Pressing OK will generate a Position List that covers a bounding box around the corners that you set.
Method 2: Use the + and - buttons in the center to select the size of an N-by-N grid, then press Center Here. Then press OK.
For either method, the dialog needs to know the correct Pixel Size. If your system is calibrated, the correct pixel size will appear here automatically; otherwise you will have to enter the correct number. It is also possible to specify an overlap between the images generated from this position list (to specify a space between them, use a negative overlap).
Interactive Stage Movements
It can be cumbersome to exactly position a microscope stage. Micro-Manager has an option (Tools | Mouse Moves Stage) that might make this easier. To use this tools, your Micro-Manager configuration must be calibrated. When Mouse Moves Stage is enabled, double-clicking in the “Live” window (the window in which the “Snap” and “Live” buttons display images) will move the stage such that the place you double-clicked will move to the center. It is possible that the stage moves the wrong direction. If so, use the camera properties ‘TransposeMirrorX’, ‘TransposeMirrorY’, and ‘TransposeXY’ (accessible in the Device/Property browser) to achive the correct stage movement (you might want to save these settings in a ‘System-Startup’ configuration group). You can also move the stage by dragging the mouse through the image (a kind of ‘Google Earth’ effect).
When the “Live” window is open, you can also use the keyboard to move the stage (Mouse Moves Stage must be enabled):

x,y modifiers |
z modifiers |
Multi-Dimensional Image Viewer
The Multi-Dimensional Image Viewer is an extension of the ImageJ HyperStack. Therefore, most ImageJ commands will work as expected on this window.
Figure 12. Acquisition data displayed in the 5D image window.
The viewer has sliders for all the dimensions you choose on the Multi-D
Acq. which include: Channels, Z-slices, XY-Positions and Time points of
the acquired images. You can playback Time Lapse sequences and adjust
the speed using the text box (set in frames/second). The red box in
Figure 12 shows where position, time, z-position, and channel for the
current image are displayed. The buttons boxed in green allow you to
Stop, Start and Pause during acquisition. Buttons boxed in blue
allow you to open the folder in which the original files are located and
also save the current image along with any adjustments to display
brightness and contrast.
Channels, Metadata, and Comments
While using the 5D-Image Viewer the ‘Histogram’ section on the Main Window has three tabs for Channels, Metadata and Comments.
Figure 13. Channels and Metadata tabs for 5D-Image View in Main
Window.
Channels
Under the Channel tab you are given various options which include:
- Scale Bar: You can choose to display a scale bar with a set position and color.
- Display Mode:
- Composite: Displays image and histogram of all channels at the same time. You also have the option to turn off any channel by unchecking the box.
- Color: Displays a single channel, depending on the position of the slider in the viewer.
- Grayscale: Displays a grayscale image of a single channel, depending on the position of the slider in the viewer.
- Histogram of Each Channel:
- You can choose to make adjustments a each channel as described in the Histogram, Brightness and Contrast section above.
- The only difference is that “Autostretch” in this case makes adjustments to all channels while in composite mode.
Metadata
In the Metadata tab you will find a box of “Acquisition properties”, which lists metadata common to the complete data set. Below are the “Per-image properties”, which lists the complete state of the microscope system at the time the image was taken. Most of these will be the same for all images, you can hide these by un-checking the box that says “Show unchanging properties”.
Comments
The Comments tab allows you to comment on the whole acquisition or an individual image. You can choose the image you would like to comment on by using the sliders in the 5D-Image Viewer. These comments will be automatically saved in the metadata and can be used to store your observations/annotations.
Files on Disk
Micro-Manager can save files in two formats, which referred to as “separate image files” and “Image file stack”.
Separate image files
Acquired images are saved to disk as separate TIFF files, each
containing a single grayscale image. The file naming convention is “img”
prefix followed by frame number, channel name and slice number
(img_00000000t_channel_00z.tif). In addition, the folder will contain
a file named “metadata.txt” that contains the metadata in
JSON format.
Image file stack
A TIFF file or group of TIFF files that contain multiple acquired images per a single file. These files conform to the OME-TIFF specification, allowing them to be easily imported into a variety of analysis applications or anything that utilizes the Bio-Formats importer.
Image file stacks are designed to be easily imported into ImageJ without the need for any special reader plugins. A stack file can be dragged onto the ImageJ toolbar and will automatically open as a hyperstack with the same contrast settings used in Micro-Manager. Any acquisition comments typed into the Multi-Dimensional Acquisition window or the comments tab of the main MM GUI can be viewed by pressing “i” with one of these files open in ImageJ.
By default, one file is created per an XY stage position (up to a maximum of 4 GB per file). In the tools-options menu, this can be changed to save all XY positions in a single file. This is especially useful for acquisitions using a large number XY positions. Since OME-TIFFs require that an identical String of XML metadata be embedded in each file in an acquisition, acquisition that have a large number of XY positions with a small amount of data at each waste space on disk by writing the same String of metadata in each file at the acquisition’s conclusion.
Writing to these files results in faster performance than writing to Seperate Image Files, in part because it minizes the number of system calls to create new files. This can be advantageous in situations where disk write speed is a limiting factor (i.e. writing to a server or collecting data at a high rate).
