Version 7.31 – download here

Version 7.31 includes a number of minor new features, and fixes a range of reported problems.

It is now possible to run an experiment using a mix of Operant cages from different manufacturers.
Taking a background picture now provides visual feedback and allows you to view the picture by holding down the ‘Take background image’ button.
Updated the ‘Start test’ button to clarify its function when tests are set to auto-start.
Made improvements to ANY-maze error reporting.
Added details of the ANY-maze support policy to About ANY-maze.
Fixed problems that could arise when a computer running ANY-maze was put into Sleep or Hibernate mode.
Fixed a bug that could prevent zone settings being altered when an existing zone was changed to be a hidden zone.
Fixed an issue that could cause some video files to be duplicated when an ANY-maze experiment was ‘Saved as’.

Version 7.30

Version 7.30 includes a number of new features, and fixes a range of reported problems.

Added a specific protocol mode for automating the Forced Swim and Tail Suspension tests. This mode utilizes an innovative technique to detect the animal’s struggle behaviour.
Added support for the new ANY-maze Operant C and Operant L interfaces. These, together with the existing Operant M interface, allow ANY-maze to seamlessly integrate with operant equipment from Coulbourn Instruments, Lafayette Instruments, and Med Associates.
Added support for the new ANY-maze activity wheel.
Track plots can now be saved as SVG vector files.
Introduced a new Dark Grey theme.
Added an option to allow animals to move on to the next stage of an experiment, without waiting for all the animals to complete the current stage.
Included a feature to correct barrel (fisheye) distortion, a common issue encountered with wide-angle lenses.
Tests now offer a specific option to allow re-tracking from the video recorded during the test. This feature not only simplifies the process of re-tracking, but also preserves any results from input and output devices.
Made various incremental improvements to tracking, including speeding up the initial detection of the animal in certain situations.
Added comprehensive documentation for all data items included in the Test Data Report. Right-clicking on an item in the ‘Protocol > Test Data Report > Data Items list’ now displays an option to view ‘Details about this item.’
Updated Stage end rules to allow for a minimum number of trials before the rule is evaluated. Additionally, for rules requiring a certain number of consecutive tests to meet criteria, it is now possible to specify the acceptable variability of the criteria.
Updated the Path Efficiency to Zone measure to report data over time.
Added a procedure action to clear all text from the display, across all procedures.
Introduced an option to dynamically show or hide chart state channels.
Improved the way in which the Protocol mode is specified by making the available modes clearer.
Improved the options for sorting the Data page spreadsheet.
The ‘Load File’ and ‘Save File’ windows now incorporate shortcuts to ‘Places’ defined in ANY-maze, such as your ‘Personal ANY-maze Files.’
Fixed an issue which could, under rare circumstances, cause ANY-maze to exit immediately, without recording any error information.
Fixed some problems which could occur when a video recording was started by a procedure.
Fixed a problem which was preventing zone labelling from working.
Fixed a problem which could cause conversion of older ANY-maze experiment files to fail when the experiment included any deleted apparatus.

Version 7.20

Version 7.20 includes a number of new features, and fixes a range of reported problems.

Improved tracking performance, especially head/tail tracking, and improved freezing detection.
Increased the maximum duration of a test to 14 days.
Added support for scoring partial exits from hidden zones, such as nose-pokes or stretch-attends.
Added an entry percentage for hidden zones, such that the animal is deemed to be hidden when this much of the animal has become hidden.
Spreadsheets that are saved or copied in CSV or SYLK formats now include units in their column titles.
Added an option to automatically set the position of a Point based on the hottest value of a heatmap. Also added measures to report where such points are located and what their hottest ‘time’ is.
Added two new informational measures: ‘Percentage of frames tracked’ and ‘Percentage of tracked frames head tracked’.
Added the ability to record an ANY-maze format video (szv) when tracking from a standard format video (such as mp4 or wmv). This is useful if a standard format video contains several tests, as it will record individual videos for each test.
Changed what happens if ANY-maze is already recording a video when a test starts and auto-recording of video files is currently enabled: The video recording no longer stops, instead the video being recorded is noted as the video file for the test.
The ‘Test video’ report now contains an option to update ANY-maze’s note of the test video file if the original file has been moved or renamed.
The ‘What to record while testing’ protocol settings now have the ability to rename all existing video files to match a specific file-name format.
Text written to the display by multiple Procedures is now displayed on separate lines – one per procedure. Removing display text simply removes that specific procedure’s text.
ANY-maze now reports if USB bandwidth is being exceeded because too many cameras are attached to a single USB root controller.
Changed the name of the ‘Electrophysiology synchronisation’ protocol element to ‘Synchronisation with other systems’, to reflect the fact that it can also be used with other things, like fiber photometry systems.
Changed AMi-2 firmware updates so that multiple devices can be updated together.
Renamed ‘Output switches’ to ‘On/Off outputs’, to be consistent with other names in ANY-maze. Also changed the option to ‘Pulse output on for xxx’ to ‘Turn output on for xxx’, to clarify its purpose.
The ‘Operant device Configuration’ window now contains a ‘Save this as the default’ check box which can be used to select whether or not the configuration being edited should become the default configuration for that interface (or interfaces).
Improved the explanation of errors that occur when trying to connect to a shared camera.
Fixed a problem which could make it impossible to select the position of a moveable zone by clicking on it, if one position was fully inside another.
Fixed a bug where menus might not open correctly when working with multiple monitors.
Fixed an error that meant that recording frequency couldn’t be changed in an experiment once a test had been run.

Added the driver for the ANY-maze USB 3 camera.
Changed Copy and Paste of the apparatus map to include the grid and ruler if all elements are selected.
Added an option to not reset a light-controller at the end of tests, so the light remains on.
Added options to the Animals protocol element to explicitly specify whether you are tracking, mice, rats, hooded rats or other animals and used this information to improve auto-start and tracking.
Fixed a problem which could prevent ANY-maze from correctly connecting to all USB cameras when many cameras were connected to the computer.
Fixed a bug which could prevent updates to a camera’s properties from being processed correctly when the camera was used by more than one video source.

Added an option to Ignore lighting changes that occur during a test
Added a new tracking option for the specific situation of tracking a white animal on a pale grey background in a standard format video.
Added reporting of the ‘freezing score’ generated by the new version-7 freezing detection.
Added a note of the ‘Test start video time’ to the Test Data report when the test was run from a video. This makes it simpler to tie up the video frames to test events such as tracking position, I/O, etc.
Updated default settings so that in new experiments, ANY-maze will now automatically record videos of all tests.
Improved the load time of the Procedure editor, particularly with large numbers of protocol items such as Zones.
Changed the way that ANY-maze deals with signing out or hibernating while the software is running, to prevent problems when another user tries to run the software.
Fixed bug which could mean that the Test Data report did not list all available result measures for selection.
Fixed bug which was preventing the ‘Number of exits from a zone’ measure from being displayed for selection in results.
Fixed some problems with incorrectly applying the region of interest when re-tracking from video.
Fixed problem where detection of the animal entering a Barnes maze escape hole could result in a short delay before the test was actually ended automatically.
Fixed bug which could mean that video files recorded during a test could be given incorrect names if the tests were manually scheduled.
Fixed a problem where Windows could mute sound cards used by ANY-maze.
Fixed problems with sound cards which could cause ANY-maze to hang after sleeping or hibernating.
Fixed a problem when printing if the default printer had a name longer than thirty-two characters.

Clarified the purpose, and improved the functioning, of the ‘Retain background images between tests’ tracking option.
Improved how ANY-maze responds when an Ugo Basile Fear Conditioning system is plugged in.
Improved how ANY-maze processes the knock-on effects on the apparatus map of changes to a video source’s region of interest.
Fixed an issue which could prevent a laser controller from automatically switching off at the end of a test.
Fixed a bug which meant that RGB8 format video images where shown upside down.
Fixed a bug which meant that all cameras were reported as supporting frame sizes of 640×480 and 320×240 even if they didn’t.

Added options to the protocol to fine-tune how ANY-maze analyses rotations of the animal’s body. (This feature is still in beta).
Improved the timing of frames in ANY-maze format (.szv) videos so they exactly align with the times of the result events stored by ANY-maze.
Improved the quality of the standard format videos that ANY-maze records (such as mp4 and wmv). Also updated how frames in these videos are timestamped so they match the time the frame was captured within ANY-maze.
Changed the Initial distance from the zone measure so that it can be analysed across time.
Updated the Data page so that when data is being analysed across time, any columns which show measures that cannot be analysed across time, are shown as
Fixed reports exported in .mhtlm format, so they open correctly in Chrome and Edge.

The system that the Help page uses to display web sites has been updated. This significantly improves the way most pages are displayed, and resolves script errors reported on some sites.
Made some improvements to setup of multiple apparatus windows, especially when using high resolution video files.
Fixed an issue which could cause a black rectangle to briefly appear when switching between items on the Protocol page.
Fixed a bug which meant a change to a Stage’s apparatus assignment method did not cause the Test Schedule Report to update.
