Hi Kan
if you draw a volumetric label you first need to sample it to the surface of that subject (mri_label2label --sample). If all you want are stats from the subject there is no need to map it to fsaverage - that is only necessary if you want to use a group coordinate system.

Dear Freesurfer Experts, I want to extract cortical features of a ROI that I drawn manually on the rawavg.mgz in Freesurfer, but i don't know how to do that. I think maybe first the lesion mask should be registered to the standard templates fsaverage, but I don't know what the command line is , could you tell me? And secondly, I should use mri_label2label to map the label to individual subject and extract the cortical features of the ROI, am I right? I am looking forward to your reply!Thanks.
Best wishes! Kan Deng
