I tried using your modified recon-all today but as soon as I try to process any
data I receive following error mess
I thought it was 4.0.3, so maybe that's not it. Can you look at the
ribbon.mgz file? You can load it as a segmentation, ie,
tkmedit subject orig.mgz -seg ribbon.mgz
aparc+aseg is suppossed to inherit the cortex from ribbon.mgz

Are you loading the one created by mri_glmfit (in the output
directory)?

Is this for a permutation test? Sorry, this is my fault. I've put a
new version here

that should fix the problem. Can you test it out?
thanks

Again, I am only asking about the sig.cluster.summary. This was a thickness

Dear Freesurfers,
is it feasible to save to nii the MR images after stripping the skull in
Freesurfer? If so, please let me know how to do it.
Thanks in advance.

You can mri_convert the output specifying the output type as -odt
short. Sorry, don't have any easy way to change the slicing.

I'm wondering whether the wmparc.stats is computed with a partial volume

Thank you,

(1) probably using mri_segstats with "--annot fsaverage lh aparc" and
specifying the --y input to mri_glmfit as the "--i invol" and specify
a "--avgwf" output to get all the subjects.
(2) Yes, you would expected it. I'm not sure what it means if you
don't see it. Maybe a bug somewhere.
(3)
In this case you would have six regressors:
1. control-offset
2. hiv-offset
3. control-age
4. hiv-age
5. control-ed
6. hiv-ed
If you want to test group thickness "regressing out" the effect of age
and ed, then you would just set the contrast to:
1 -1 0 0 0 0 0
Note that this will test it at ag
This cmd is not going to work. I don't think we have a way to convert
between the two. Sorry,

Yes, this is what our group analysis tools do. You can find tutorials
on the wiki. You'll probably start with mris_preproc.
