Hi FreeSurfer expert, I am interested in a particular region of the Desikan-Killiany atlas and I'd like to use it as an ROI image mask in my fMRI analysis.
Could you please suggest how I can do that? From here (http://ftp.nmr.mgh.harvard.edu/fswiki/CorticalParcellation), I see that the DK atlas files are located here: $FREESURFER_HOME/average/?h.curvature.buckner40.filled.desikan_killiany.gcs Question 1: how can I read this GCS file? Question 2: After I read this GCS file, how can I create an ROI image mask? I am thinking to use the WFU PickAtlas to create an ROI (http://fmri.wfubmc.edu/software/PickAtlas). Would it be a good fit? Thanks! Daniel -- Yung-Jui "Daniel" Yang, PhD Postdoctoral Researcher Yale Child Study Center New Haven, CT (203) 737-5454
