Hi FS experts and users
I have done the each subjects' surface
regestration on fsaverage surface, and merge all of them into a *.mgh. Group
analysis is also completed.
Now I have two questions:
1,I want to extract the VtxMax vertex number
thickness for all subjects. The VtxMax vertex number can be got in the
*.sig.cluster.summary file. And it represents the most significant vertex in
that cluster. I search my question in google and find these scripts which maybe
helpful:
for i in `seq 1
$numsubject`
do
mri_convert --frame $i y.mgh
$SUBJECTS_DIR/fsaverage/surf/lh.$i.mgh
mris_convert -c $i.mgh $SUBJECTS_DIR/fsaverage/surf/lh.inflated
lh.$i.asc
done
I got the lh.*.asc file and open it. there are
five columes in this file: I guess that: first colume is vertex number, the
2nd-4th columes represent MNI coordinates in surface, and the 5th colume is
thickness of this vertex. If I want to deal with my 1st question, all I
need to get the lh.*.asc file and search the specific vertex number in this
file. All of above, is there anything wrong?
2, I created a surface mask, and want to extract
the average thickness value in this mask for every subject. How can I complete
it?
Any reply will be highly appreaciated.
Thanks
All the best.
