Hi freesurfer experts,

I currently have a set of cortical labels that are the result of a high-resolution parcellation of the standard aparc.annot labels (via the ‘connectomemapper’ software). I would like to extract the gray matter ROIs that correspond to these labels, and I understand that this requires a method to ‘propagate’ these labels through the gray matter. I have so far been unsuccessful – ‘mri_label2vol’ seems to only give me that pial or white surfaces, as opposed to the gray matter bodies. Does anyone know how to accomplish this?

Thank you very much,

David Grayson
