This release is the version used for HCP Development and HCP Aging data ICA-FIX and MSMAll processing.

Added features:

  • Enabling creation of cleaned movement regressors to apply to spatial ICA-FIX (sICA-FIX) cleaned fMRI data. (#164)
  • Extend the checking of the subcortical segmentation (originally #163) to evaluate, per individual subcortical structure and for the brain mask (at both 1x and 2x voxel resolution dilation), the number of voxels missing, those that overlap, and those that fall outside the Atlas (#165).
  • Changes in sICA-FIX to reduce memory usage when applying hp filtering, estimating the dimensionalities of structured and unstructured noise, and computing variance normalization on volume files (#168).
    Note: the biggest memory reduction is with interpreted matlab mode, with a smaller benefit for compiled matlab mode.

Known Issues:

  • There is a bug in the naming of the column headers of the .txt file that quantifies the missingness/overlap of the subcortical segmentation, which was subsequently fixed with f4afdc5 and 64971e3.
  • Testing revealed that using Octave mode for multi-run ICA-FIX does not always stably converge. Using Octave mode for multi-run ICA-FIX is not advised at this time.
  • Input NIFTI files with a TR that does not use units of seconds result in incorrect TR of outputs - please set the TR in units of seconds before processing (#124)
