Hi Jo,
All the preprocessed fMRI data is in HCP-standard volume (MNI152) or
grayordinate space.
Those are contained in ${subj}/MNINonLinear/Results
The subject-specific FreeSurfer labels transferred to this space and at
the same surface mesh resolution are contained in
${subj}/MNINonLinear/fsaverage_LR32k
As for the 'wb_command' option to extract an average timeseries within a
specified label, Matt or Jenn will have to chime in with that.
cheers,
-MH
