Hi Ines,
use the mgh route. The "vol" is actually the vector of thickness values,
with one entry per vertex on the surface.

Hello,
I was trying to create a cortical thickness map with constant values in
order to perform some tests. At first I tried using mris_convert. I
converted my thickness file into ascii:
mris_convert lh.thickness lh.thickess.asc
then I used matlab to change all the values in the last column to 2,0. I
tried to convert the ascii file back to surface file by doing
mris_convert lh.thicness.asc lh.thickness
but I got "Segmentation fault". How can I convert may ascii file into a
surface one?
After failling to acomplish this, I tried using the save_mgh and load_mgh
file, nevertheless I'm not quite sure which input values are needed. Where
can I put my fake values in the save_mgh file? And what is "vol"?
Thanks,
Ines
