Hi Darren,
the ico and average7 are about the same computationally. However, it is
more convenient to use average7 it has a surface that you can directly
render the results on. With ico, you'd still have to run mri_surf2surf
to convert it to another surface.
I'm not sure what you're trying to
Dear Bruce et al,
my query is about how to register cortical surfaces across X subjects, given
that we have modified the usual left/right surface separation.
Some time ago we discussed how to extract a complete cortical surface,
rather than the left/right hemi surfaces. The purpose of this
Hi Darren,
that's pretty much the way I generated the lh and rh templates we use.
There's a binary named mris_make_template,which you probably have, that
will take a bunch of surface models and construct a template (.tif) from
them. You'll have to name the individual surface lh or rh, since
Thanks, Bruce.
mris_make_template --help stops at 'valid options are:' :-(
One of the input parameters is a surface name - I suppose 'orig', 'white',
'pial' etc are valid. I'm not sure what surface to specify; is it 'sphere'
or 'inflated' or something else?
Cheers, Darren

Hi Doug et al,
from looking at the help on mris_surfglm it appears that vertices in the
analyses are not as dense as those from the subject surfaces. I'm guessing
that using the ico surface with 7 iterations of refinement (lots of
vertices!), you then locate the nearest vertex in each subject
