We don't have something explicitly to do this, but you can run FDR on it
using either mri_fdr (use nomask for the mask) or you can load the
sig.mgh file into matlab and run it there, eg,
sig = MRIread('sig.mgh');
p = 10^-abs(sig.vol);
fdrthresh = fast_fdrthresh(p);

Hi Meaghan
it looks like the white surface is pretty accurate but the gm doesn't get
out far enough. I would play with some of the expert options to

can try it out and see if I can improve things and get back to you.
