Hi doug, Not a huge difference. It does not alter the subsequent cluster. thanks for the clarification though... shantanu

How big? They use different programs so, depending on how big, it might just be a precision issue.

hi doug, i notice slight differences in numbers when using fscalc vs. fscalc.fsl for calculating the z-score map\ I am just curious why it may happen thanks in advance, shantanu

Use mris_preproc to collect your normal subjects into a single file. Then use mri_concat to compute the mean and stddev of your normals mri_concat file.mgh --mean mean.mgh mri_concat file.mgh --std std.mgh Then compute a z-score for your subject (after transforming to fsaverage space): fscalc subject.mgh sub mean.mgh div std.mgh -o z.mgh Visualize tksurfer fsaverage lh inflated -overlay z.mgh

Hi FS experts,
Sorry if this is a newbie question.
I want to display how an individual patient's crtical thickness varies from the normal group average, vertex-by-vertex. What is the commandline to do that? I want to display the overlay on MNI152 instead of fsaverage.
Thanks in advance, Shantanu
