Version Compatibility

Although the Toolbox can generally open files from older versions, it is not guaranteed that the results obtained in different PhysioData Toolbox versions are completely equal, nor that newer versions of PhysioAnalyzer modules properly parse old parameters. It is therefore not advisable to directly compare data analyzed using different Toolbox versions; i.e., only use one version of the Toolbox for a given study, if possible. In any case, always double-check the PhysioAnalyzer data, settings and user-corrections when loading older files, and always validate the results.

Change Log

PhysioData Toolbox v0.7.0 (Latest)

PhysioData Toolbox version 0.7.0 contains several user experience enhancements and under-the-hood improvements. It was released on May 6th, 2025. Download it here.

  • New file-conversion features:
    • A PyGaze interpretation mode has been added to the Tobii and EyeLink converters.
    • The Tobii converter can now convert plof files, allowing analysis of Tobii Pro Lab pupil size data.
    • The EyeLink converter can now parse DataViewer trials.
    • The BIOPAC converter now supports acq files up to version 5.0.8.
    • Generic eye-tracking and signal TSV file converters have been added.
    • Many more.
  • New analysis and processing features:
    • The Blood Pressure module now features enhanced UX and NIBP-100E event detection.
    • The ECG module now outputs a list of all IBIs.
    • The epoch generation engine can now use the AFTER and BEFORE keywords.
    • The Epoch Builder can now highlight all epochs generated by a specific definition row. This is activated via the definition table context menu (right-click in the cells).
    • Eye-tracker metadata is now included in the analysis output.
    • Many more.
  • Other new features:
    • he documentation has been improved.
    • The GUI has been simplified and now provides more real-estate for graphs.
    • The Toolbox no longer collects any anonymous usage data–no analytics is performed at all any more. As such, feedback on usage is greatly appreciated and will help motivate the mobilization of development effort.
    • The PhysioData Analyzer window menu and the settings dialog now contain direct links to relevant documentation.
    • Many more.
  • Bug fixes:
    • The File Converter table (and others) no longer bug-out when the DPI is not 100%.
    • The Skin Conductance module no longer crashes when exactly one SCR is detected.
    • Many, many more.

PhysioData Toolbox v0.6.3

PhysioData Toolbox version 0.6.3 contains several minor bugfixes and improvements. It was released on Jan 27th, 2022. Download it here.

  • Bug fixes and improvements:
    • Fixed an issue that may cause referenceable events to be plotted in an incorrect graph.
    • The Pupil size module’s fast-mode has been improved and documented (link).
    • The minimum selection size has been decreased (narrower areas can now be selected).
    • Resampling timestamps (in the time_Epoch variable) are now rounded to the nearest 0.0001 second to avoid floating point errors from preventing equivalent time-points from being grouped together. Additionally, the variable resampled_index has been added, which indicates the index of the resampled data-point.
    • Other minor GUI corrections and framework updates.

PhysioData Toolbox v0.6.2

PhysioData Toolbox version 0.6.2 contains several improvements to its framework, user-interface and documentation. It was released on Dec 23rd, 2021. Download it here.

The most user-relevant updates are:

  • New converters:
    The MRI scanner Physlog and BioSemi converters have been updated and reintroduced.

  • Bug fixes and improvements:
    Version 0.6.2 contains several bugfixes, including:
    • Resampling when files contain multiple modules of the same type no longer crashes.
    • The Skin Conductance module no longer crashes when analyzing epochs with a duration of 100 ms or less.
    • The Biopac converter no longer saves ‘New Rate’ events as labels.
    • Fixed an issue causing the Data Previewer to not regenerate the data.
  • New features (beta):
    • The ECG module now allows users to manually add R-peaks.
    • The ECG module can now visualize superimposed QRS waves for easier anomaly detection.
    • The Pupil Module now also supports ‘Fast-Mode’ for easier corrections.
    • The referenceable events table (in the Raw Data Viewer or the Epoch Builder) can now also show a summary of the events.

PhysioData Toolbox v0.6.1

Contains all the improvements of v0.6.0, as well as a minor bugfix relating to the Gazedata Converter. It was released on July 8th, 2021. Download v0.6.1 here.

PhysioData Toolbox v0.6.0

PhysioData Toolbox version 0.6 contains several improvements over v0.5.

  • New epoch definition rules:
    PhysioData Toolbox Version 0.6 contains a completely new epoch definition rule-set, which makes it possible to define multiple epochs using the same rule. Additionally, the use of regular expression and integer ranges for marker/event matching has been implemented.

  • Various bug and framework fixes:
    The new version features a partially refactored codebase, with several bug-fixes and performance improvements.

  • SCR detection:
    The Toolbox now detects Skin Conductance Responses.

  • New example datasets:
    Included now are new example datasets.

  • This website:
    The PhysioData Toolbox documentation has been updated and moved from a pdt document to this website.

  • Less converters:
    The MRI scanner Physlog and BioSemi converters have been removed until a future release.

PhysioData Toolbox v0.5.0

Versions older than 0.6 are considered legacy. A zip file containing PhysioData Toolbox v0.5.0, including all documentation, can be downloaded here.
