Hi Thomas,
Thanks for your reply.
The fsaverage directory I have for fs v 5.1 does not include the lh and rh Yeo2011_7Networks_N1000.annot files. I only have this in the 5.3 version of fsaverage. Can I still use the 5.3 version annot files or would I need a seperate set processed with version 5.1?
Kind regards,

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/
