Hi Bronwyn, You raise a good point. You can consider creating a cortical mask using aparc+aseg.mgz and use that to mask the networks.
However, another approach (which might be more accurate) is to take cortical networks in fsaverage space and transform to your subject's surface and then transform into your subject's volume: # Transform from fsaverage to subject's surface >> mri_surf2surf --srcsubject fsaverage --trgsubject yoursubject --hemi lh --sval-annot *lh.Yeo2011_17Networks_N1000.annot* --tval $SUBJECTS_DIR/yoursubject/label/*lh.Yeo_17Network_native.annot* # Transform from subject's surface into your subject's volume (I am not super sure about this. You probably want to double check the output is correct) >> *mri_label2vol --annot lh.Yeo2011_17Networks_N1000.HS_001.annot **--o outfile.nii.gz --hemi lh --subject HS_001 **--regheader* --Thomas On Wed, Jun 22, 2016 at 8:25 AM, Bronwyn Overs <b.ov...@neura.edu.au> wrote: > Hi Mailing List, > > I am attempting to apply the Yeo 2011 7-network fucntional parcellations > to a set of fs MRIs processed with v5.1.0.
