Hi, Bruce
Sorry for the late reply as I was trying to figure it out by myself.
I mean the average of the subjects in the volume space that were used for
generating the surface template. Actually I kind of found a volume average in
the mri folder named as T1.mgz that seems to correspond to the surface template
for the non-human primates. Perhaps because my ?h.white and ?.pial surface
files do not have the identical origins as that of the volume template, when I
used the function "mri_surf2vol" to project the mgh surface file to the volume
average, I always got the outputs telling me there is 0 hits. I tried to
diagnose it by projecting the ?h.white and ?h.pial to the volume using
"mri_fill" and I got an empty volume. I then tried to project ?h.inflated to
the volume space using the "mri_fill" and this time, I got a mask in the output
volume space. Therefore, i suspect that there is a mismatch of the origins
between the ?h.white and the volume template in the mri folder.
Could you please show me what are the best strategies to correctly project the
mgh file to the volume template in the 'mri' folder?
Many thanks
LongchuanÂ

Hi Longchuan
what kind of volume template do you mean?
