Release 1.10.0 (April 22nd 2025)
This update includes multiple new features and is one of our biggest yet!
Python (pypixxlib)
Added functions to set and get the PROPixx LED intensity options (100%, 50%, etc.).
New demos have been added to the documentation. More information here: Python Documentation
macOS ARM (m1, m2, m3, m4) Support
Our files and installer now support the new Mac architecture. For MATLAB, the new file extension is mexmaca64. For Python, the package will automatically install the right version. Please note that LabMaestro is not currently compatible with macOS.
Ubuntu Support
With Ubuntu 20.04 being end-of-life, we now support Ubuntu 22.04 and 24.04 on X-Server. This is the last version to support Ubuntu 20.04.
LabMaestro Changes
General
Extra information on many elements of LabMaestro has been added in the form of tooltips.
Warnings added in device configuration when trying to use features not available (ex, Analog on a “Lite” device).
Clearer error messages have been added for specific issues.
Added a new button in the SetVariable command to open the timeline variable menu.
UI Improvement to select keys in the WaitForInput command.
Support the newest VPixx 3DPixx glasses.
Test patterns can now be closed using the escape button.
Global Variables and Expressions
The Main Display is available in Expression. You can use Display to query information about the display directly in expressions (ex, Display.RefreshRate)
The Frame Number is available in Expression as frameNumber. This number represents the number of frames since the start of the TRIAL.
You can access experiment information (found in ExperimentDesign) directly in expressions (e.g. =SubjectID)
Colors can be used in expressions.
Timeline variables support colors as a type of value.
More information on expressions can be found here: Values and Expressions
TRACKPixx3 Calibration Tools
The pupil black threshold has been removed and is now automatic.
New Tracker Commands in Expression: isFixating checks if the subject is currently fixating, gazeAt checks if the subject is looking at a specific spot on the screen, and Fixation performs both functions.
More information here: Values and Expressions | List-of-currently-supported-operations-(as-of-version-1.10.0)
TRACKPixx Setting Tuner
The TRACKPixx’s settings, which must be set for each subject, can now be automated to help you set them up and assist with the focus.
More information on this can be found here: Using the TRACKPixx3 within LabMaestro | NEW!-TRACKPixx3-Settings-Tuner
Random Timeline Variables
Timeline variable values can now be generated randomly. A seed is generated at the start of the experiment and can be reused to generate the same set of numbers again or changed to produce a different set.
New device communication behavior
Commands that should be communicated to VPixx devices are now synced to the next video frame, rather than being applied immediately. This feature cannot be disabled. However, a new pre-launch warning will verify that a device is connected and receiving video before this feature is turned on.
We now batch all register commands to be executed at once. This simplifies the number of communications to the device to one. All the commands are being applied at the next video frame. This feature is enabled by default, but can be disabled in the settings if you prefer to apply the commands immediately.
New device setting restoration
New setting to allow restoring device properties after an experiment (enabled by default). For example, if your experiment is in 1440Hz, then the PROPixx will change to that mode during the experiment but revert back to its previous state.
New Color Handling
The new color picker enables you to select your color in multiple formats, ranging from specifying luminance and chromaticity to choosing a standard RGB value.
New tools enable you to calibrate your monitor to linearize your gamma and display colors in your preferred color space.
More information on these tools and the supported color space here: Colors in LabMaestro
Monitor calibration
The new monitor calibration tools enable you to automatically calibrate your display to linear luminance if you own an X-Rite i1 Display Pro3 (Pro2) or an i1 Display purchased from VPixx. We also allow manual entry of gamma to simply linearize any display.
More information here: Gamma Calibration
Color Measurement Tools
If you own an X-Rite I1 Display Pro or I1 Display purchased from VPixx, you can now access a widget to take the luminance, chromaticity, and spectral measurements directly in LabMaestro.
More information here: X-Rite Measurement Tools
Support for High Bit Depth Modes
You can now directly use high-bit-depth video modes (formally known as M16, C48) in your LabMaestro experiment. Demos have been added and can be found here: High Bit Depth Rendering with VPixx Devices .
Support for High Refresh Rate Modes
You can now directly use high refresh rate video modes (formerly known as QUAD4X and QUAD12X) in your LabMaestro experiment. Demos have been added and can be found here: High Refresh Rate Rendering with VPixx Devices .
Support for 3D Modes
You can now directly use 3D video modes (Top/Bottom, grayscale 3D (RB3D), blueline) in your LabMaestro experiment. Demos have been added and can be found here : [In construction]
Data Visualization
The end-of-experiment data viewer now allows you to view digital and analog data, in addition to eye-tracking data previously available.
More information on data visualization here: [In construction]
Pixel Mode command
A new command called Pixel Mode can be used to enable pixel mode and set the top-left pixel to the desired value for the required trigger.
More information here: Commands | Pixel-Mode
Abort Command
You can now complete your experiment using the Abort command.
More information here: Commands | Abort
Digital and Analog Log Commands
New commands have been added to monitor digital and analog signals directly within your experiments. More information on the schedule commands can be found here: Commands | Schedule-Commands
Resolution Choices (EDID)
You can now select the resolution that your device should use. This used to be the “edid” command in VPutil. A single resolution is now available. When you select your resolution, follow the on-screen instructions to restart your devices.
More information on this can be found here for the PROPixx: Using the PROPixx within LabMaestro | Setting-up-the-PROPixx-Desired-Resolution-(EDID)
Component Library
We have added new icons to the component libraries as well as a complete search bar. You can set the size of the library using the scroll bar at the bottom.
More information on the components page here: Components
Flicker Waveform
You can now use the flicker waveform directly on a region. If this is enabled, it will behave as if a uniform pattern is applied to the region, causing flicker between the peak and trough color values.
A new option named fixed time interval (enabled by default) allows the flicker to recalculate its subsequent value at a constant rate (1/framerate). This is useful for the RIFT method.
More information on the flicker waveform here: Patterns | Pattern-Flicker-Waveform
Simulator
PROPixx can now be simulated. However, it is considered a DATAPixx3 accessory connected to the Videobahn. Most functions are supported, including video mode and register settings.
Bug fix
Simulated tracker data now starts at the right timetag.
In the experiment design, the By Design session fields can use validation rules.
Experiments launched on extended displays now start in full-screen mode properly.
PPI measurement tool now shrinks as well as extends!
You can now use global variables in color regions.
Tracker calibration timer before start has been changed to be visible on a white calibration screen.
Unused warning for resources now checks properly if a resource is not used.
Duty Cycle time cannot be 0 for a digital output trigger.
Simulated devices cannot have their simulated firmware updated.
You can no longer select “missing link” as a resolution. This is reserved for when you do not have video input.
Fixed the granularity on the TRACKPixx LED Intensity slider.
VPutil warning issue when a device was connected has been fixed. No more version mismatch if you have the right version installed!
The Digital IO tester now warns users when using drive strength to ensure it is used with a RESPONSEPixx.
Solid and Full colors were inverted; it has been fixed.
Logging of digital inputs will now be stopped when an experiment ends or is stopped.
Fixed an issue with Shape Mask when using cm or degrees of visual angle.
Fixed an issue with the Arc region where changing the angle would cause it to be incorrectly drawn.
Fixed an issue where a simulated TRACKPixx’s data had the wrong values for digital outputs.
Fixed an issue where a simulated TRACKPixx’s schedule would not stop when stopped.
Fixed an issue where digital inputs were not recorded as described.
WaitForInput now reports all events.
Fixed a crash when saving TRACKPixx /mini data.
Screens are now bound with their serial number if that information is available from the manufacturer.
Fixed an issue where copying an image from the web could cause LabMaestro to crash.
Fixed an issue with non-looped audio on the simulator, where any audio would play indefinitely.
Fixed an issue where starting a calibration with no tracker connected would cause the experiment to crash.
Happy experimenting!
