Hi,

I asked about this last week, and had a nice discussion with Doug, but somehow in that we never got the answer to my original question.

When FreeSurfer saves t-values (in F.mgh), what is it actually saving? The numbers in the file do not have a t-distribution (even when the source data for the glm is random noise). Is a transform applied to the t-values before the write, as is done with the p-values?
