Dear all, I've created non-overlapping ROI masks using
mri_label2vol --seg aparc.a2009s+aseg.mgz --regheader orig.mgz --o rois.nii --temp sub.nii --subject 01 Now these ROI masks are actually quite conservative concerning grey matter vs. other structures, i.e. they are only on the grey matter. I've seen more liberal masks e.g. here: https://surfer.nmr.mgh.harvard.edu/fswiki/CorticalParcellation_Yeo2011 I would like to create similarly liberal non-overlapping ROI masks for all ROIs in the voxel size defined by the image in --temp, but excluding specific tissue types such as white matter, CSF, and other non-grey matter tissue. What would be the best way to do so? Cheers, Martin
