Hi all, I have obtained laterality indices using xhemi analyses and would like to use FDR instead of the mri_glmfit-sim suggested in the xhemi instructions. I know to get the FDR threshold from tksurfer, but I want to restrict the clusters to a certain cluster size. Based on a previous thread ( http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg23866.html ) I think this should be done using mri_surfcluster but I am having trouble with the actual commands. I've tried this but it doesn't seem to work:
mri_surfcluster --in glm.lh.lh-rh.thickness.BV.LI.mgh --thmin 2.54 --ocn ocn.mgh --sum sum.dat --sign abs --minarea 20 --surf fsaverage_sym --hemi lh the error = srcsubjid must be supplied If I'm performing this on a group file (not individual subject), what would I even input as the subjid? Or do I have this totally wrong? Thanks! Krista
