It is not a z-value. It is -log10(p), so -log10(.01) = 2

Hi Doug,
Thanks! I didn't realize that the threshold is a negative exponent to a base of
10!
Just wondering, is there a webpage that I can read to understand why FreeSurfer
chooses this exponent approach instead of z-value?
Also are 1.3, 2.3, 3.3, 4.3 two-sided, and 1, 2, 3, 4, one-sided? For
Hi Daniel, there is no difference. Once you select the appropriate
threshold, it does not matter whether it is a z-field, p-field, t-field,
or -log10(p)-field because it gets binarized.

Hi FreeSurfer Experts,
On this page
(https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QdecMultipleComparisons),
it says: In particular, thresholds of 1.3, 2, 2.3, 3, 3.3 and 4, corresponding
to p-values of 0.05, 0.01, 0.005, 0.001, 0.0005 and 0.0001, which are common
thresholds.
