Hi, Ray
mri_average goes through two steps.
The first step does not use RAS. It uses a simple principle axis
alignment algorithm.
(Note that this means that the voxel size must be uniform.)
The second step which makes the alignment more accurate uses the
rasToVoxel /
voxelToRAS transform.
I wouldn't use mri_average to mtion correct - I wrote a preliminary
version and never really tested it much. You're better of with FSL.

I have a set of subjects whose pial surfaces are poorly reconstructed
because of bad gray/csf contrast. Specifically, the pial surface
doesn't seem to deviate from the white matter surface by much more than
.5-1 mm. Is it possible to artificially grow the
Hi Jeremy,
there was a version of mris_make_surfaces that had a bug resulting in this
behavior. Try updating to the latest version and see if that helps.
cheers,

Is there a way to create your own annotation file with a certain group of
labels?

use the attached files (2 matlab,1 colortable) to make your own
annotations from a series of labels. it assumes some things about your
label naming convention. to use, i recommend the following steps:
1. examine colortable file and add or subtract lines, or change region
names and/or colors to
Hi Stefan,
there are tools for downsampling the mesh in tksurfer. Note that this
doesn't preserve any connectivity - it only generates a reasonably uniform
point sampling of the original vertices. Matti: could you describe to
Stefan how to wrote out the .dip and .dec files?
