Hi Liang
yes, that information is encoded in the .tif file that is the target of
the registration. You can use mrisp_paint to copy a frame out of
$FREESURFER_HOME/average/?h.average.curvature.filled.buckner40.tif
the tif file is 3 sets of triplets in different frames. The first is the
mean
Dear Bruce,
Thanks for pointing me those information. That .tif file includes the mean
and variance for the population sample that was used in Freesurfer. I would
like to get similar measures for our own subjects. I think I could use the
surface file (like surf/?h.sulc) in each subject folder to
You can just run mris_preproc --meas curv --o stack.mgh ...
This will give you a stack from which you can compute the mean and stddev
mri_concat stack.mgh --mean --o stack.mean.mgh
mri_concat stack.mgh --std --o stack.std.mgh

yes, you can use mris_make_template to generate these results (it's what
we used to create the tif files in the first place)

Thanks Bruce. one more question:
This is my command (5 subjects)
mris_make_template lh sphere.reg subj1 subj2 subj3 subj4 subj5
./Temp5subj.tif
where I select sphere.reg as sphere surface. I assume 1) that the generated
template Temp5subj.tif is in the Freesurfer buckner40 spherical space and
Hi Liang
the sulc is the integrated signed dot product of the movement vector with
the surface normal during inflation. It reflects large scale geometry
better than ?h.curv, which is the spatially smoothed mean curvature. If you
are using sphere.reg you can probably specify -norot so it
Dear FS folkers,
I am working on a functional probabilistic atlas. I find that some
functional regions (particular along a big sulcus) show quite high
probability value over a large sample, whereas the probability for some
regions are quite lower. I think this disparity could be accounted for by
