Not sure. Are you visiting vertex 10738 ?

Hi FS developers,
I have used mri_glmfit-sim to do multiple comparison like below:
mri_glmfit-sim --glmdir lh.thickness.0.glmdir --cache 3 abs --cwp
0.05 --2spaces
and in the lh.thickness.0.glmdir/group.diff directory, I got some
output files, some of which were:
cache.th30.abs.sig.cluster.summary
cache.th30.abs.sig.cluster.mgh
When I open the file cache.th30.abs.sig.cluster.summary, I see its
content like below:

My question is: what are the values of the Max column? I thing they
are –log10(p), and the file cache.th30.abs.sig.cluster.mgh should also
have this kind of values saved. But when I use freeview to view the
lh.inflated surface with overlay file cache.th30.abs.sig.cluster.mgh,
and use the “configure” button to configure the “Overlay” threshold, I
cannot find the Max value of overlay displayed on the inflated surface.
Could you please explain to me why I cannot see the Max values (shown
in the summary file) as the overlay on the lh.inflated surface?
BTW, in another experiment where I use mri_surfcluster to generate
both summary file and overlay file, this problem does NOT exist.
Thanks!
Xiaojiang
