External Email - Use Caution
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:
# ClusterNo Max VtxMax Size(mm^2) MNIX MNIY MNIZ CWP CWPLow

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
