Hello all
Are the norm.mgz and aseg.mgz volumes already aligned
to talairach standard space ?
I have read on the freesurfer tutorial that the
transformation is computed and stored in
transforms/talairach.ita but it is no applied to the
initial volume. I would like to get the segmentation
result
use mri_convert and apply the talairach.xfm (-at I think). Make sure to
use nearest nbr resampling for the aseg.

I have read on the freesurfer tutorial that th
you can use mri_label2vol to sample the aparc+aseg.mgz into the
functional space, then run mri_segstats on it to give the number of
functional voxels in each label. Or you can just look at the volume of
each label and divide by the volume of your functional voxel.

I followed the Fsfasttutorial to learn fsfast. But when I run preprocessing
(preproc-sess -s mgh-101.1 -fwhm 5), I always get following error message

hi,
Under freesurfer, how can I force mri_watershed to create 5012 triangles
(ico 4) instead of 20480?
cheers

You will need to use the most recent development version

Nima,
There is no flag to mri_watershed to allow this, but you can trick it by
doing the following:
cd $FREESURFER_HOME/lib/bem
mv ic5.tri ic5.bak
ln -s ic4.tri ic5.tri
This will force usage of ic4.tri, which has 5120 triangles.
