Dear Dr. Douglas,
Thank you so much.
I have difficulty to understand z map is essentially an infinite # of
subjects.
Before smooth, there is no GLM analysis. Does the smooth include in the GLM
process?

Correct. This is no different than, eg, a t-test. Look in the back of a stats
book from the 1950s and you will find a table of t-ratios and corresponding
p-values. Obviously, they did not have access to any of the data being analyzed
today:), but the tables are still valid.

Dear Dr. Douglas,
Thank you so much for your detailed response.
The simulation here is to get the probability of a maximum cluster that
size or larger in the cached CSD files. It checks the probability of the
cluster size but have nothing to do with

That will use the pre-computed ("cached") CSD files distributed with
FreeSurfer. This used 10,000 iterations.
