Hi Doug,
Although in principle, yes this is the idea, we have a set of labels that aren't actually in the aparc+aseg file (basically a set of high-density subdivisions of those regions). The only problem is that the labels I have are just in "surface-land." I am wondering, once I have the surface labels, is there a way to re-propagate them back into the gray matter?
Thanks again,
David

Do you just want the label in the orig volume space? If so, just use the labels in aparc+aseg.mgz doug

what was your label2vol command line? doug

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
