I don't have anything explicitly that will compute a map of z-scores, but you could do a two "group" analysis with your subject as the only one in one group and then do a group analysis. Alternatively, you can transform you individual to the fsaverage space (mri_surf2surf), then compute the z using fscalc.fsl. You'd have to compute the group mean and stddev using mri_concat (--mean and --std), then use fscalc.fsl, something like
fscalc.fsl --surf fsaverage lh lh.thickness.fsaverage.mgh -sub groupmean.mgh -div groupstd.mgh zscore.mgh doug On Wed, 9 Jun 2010, Michael Scheel wrote: > Dear FS experts, > > could someone advise on how to create from an individual thickness file > (?h.thickness) a standard deviation or z-score map of the thickness with > respect to a control group. > > Thanks, Michael > _______________________________________________ > Freesurfer mailing list > Freesurfer@nmr.mgh.harvard.edu > https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer > > > -- Douglas N.
