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,
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
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,

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

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