Description

The updates to CPAC in this new version include:

  • CPAC now offers De-Spiking as an option in nuisance regression, which regresses out the impact of motion-induced artifacts from the functional timeseries from volumes exhibiting motion greater than a specified threshold, without removing those volumes.

  • Users can now select which Framewise Displacement (FD) calculation to use (Jenkinson's or Power's) when applying the motion threshold for either Scrubbing or De-Spiking.

  • CPAC can now automatically select a Framewise Displacement (FD) threshold based on a percentage value provided in the pipeline configuration. For example, if provided 5%, CPAC will select a cut-off derived from the top 5% of highest-motion volumes. See the User Guide for more information.

  • Scrubbing has been moved to the Nuisance Regression tab in the GUI's pipeline configuration editor. The pipeline configuration YAML keys have changed for scrubbing settings. See the User Guide Nuisance Regression page and the sample pipeline configuration file for more details.

  • Re-introduced the ability to stop pipeline runs easily from the GUI.

  • Fixed a bug in the data configuration (subject list) builder that would cause non-NIfTI files to be included if the user did not explicitly define the file extension in the file template.

  • Fixed a bug in the data configuration (subject list) builder where some fields would not get populated when re-loading the settings in the GUI.

  • Added better error-catching and messages in nuisance regression which warn the user if nuisance parameters are too stringent for the regression to complete properly.
