Dear FreeSurfer Developers,
I'm attempting to correlate the sulcal depth information present in the ?h.sulc files with activation in particular brain regions during an overt language task in an fMRI paradigm. For this matter, a dataset was gathered throughout the years with several subjects and the cortical reconstruction process (as described in: https://secure-web.cisco.com/1nqW39ubw2AyrvIfDDZNWB66KB47XSeO6tS5QZO8RBYGIE_...) was performed at the time of data acquisition. However, for subjects where recon-all was run in different FreeSurfer versions (5.3.0 or 6.0.1), I get an order of magnitude difference in the sulc values in the ?h.sulc volumes.
I've searched the list and the official FreeSurfer Release Notes (https://secure-web.cisco.com/1vUPpLJpZFWtBAPAZsBnTOCfqihx6dgklkyFygBvPMdyx7e...) and found no information of a change of magnitude in sulc values. Does anyone have any thoughts on how to trouble-shoot this one?
1) FreeSurfer versions: freesurfer-Linux-centos4_x86_64-stable-pub-v5.3.0 & freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.1-f53a55a 2) Platform: Linux blue 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u3 (2015-08-04) x86_64 GNU/Linux
Kind Regards, Francisco D. Guerreiro Fernandes
