Allright, if the option --interp nearest is used the output is as given in a
previous post
(http://www.mail-archive.com/freesurfer%40nmr.mgh.harvard.edu/msg35148.html).
After applying --interp trilin the output is:
mri_vol2surf --mov /.../f001.nii --reg /.../register.f001.dof6.dat --interp
Don't use --projopt

After applying --interp trilin the output is:
Well, there is no difference between trilin or nearest. mri_vol2surf displays
segfault regardless which option I use (trilin or nearest).

However, let's forget about this question. I need to address something else and
until that is finished it does not matter.

Can you send your commandline with --interp as well as the terminal output?

Allright! The only point I would like to emphasize is:
Regardless if option trilin or nearest is used I need to interpolate the
functional data to the structural image of the subject. This might be due to a
feature of the function build_sample_array in the mri_vol2surf source code.
In this
I don't understand what the question is. If you need to interpolate,
then use --interp trilinear

Sorry for this question, but now I am confused. Do you mean that I should not
use projopt and just use the interpolation? If so why should I not use projfrac?

You can use --projfrac (which can perform an interpolation with --interp
trilinear)

Well, I need to use that option. In this case I will just interpolate to the 1
mm grid and proceed this way.

Actually, this uses mri_compute_volume_fractions and
mri_compute_intensities to build partial-volume models of the tissue and
then estimate them with projopt. I haven't tried this code in a few years
so you are somewhat on your own. We are hoping to clean
Hello,
I found an option in mri_vol2surf for which I could not find a documentation.
The option is called:
--projopt
It would be nice if somebody could give a description of this option.
Respectfully yours

This is something BF added Sept 1 2009:
added --projopt switch to do optimal linear estimation of gray matter
values given a set of precomputed gray matter densities.
I don't know what it would mean beyond that

Please help me with this issue:
If I apply mri_surf2vol to a single volume of unprocessed epi-data, it
results in a segmentation fault. It works if I apply mri_vol2vol for
registration of epi and anatomy, but than an interpolation is
involved. I would like to avoid the interpolation and apply
what is your command line that is seg faulting? What is the terminal output?
