ops, it seems the comments inside the dpxwrite.m no longer reflect what
it does. You probably don't need this, but anyway, the version attached
is more up-to-date.

Hi Pedro,
There is probably a way to do that using FS tools from the command
line, but the attached script should do the same. The result is a
"data-per-vertex" file, which is the same as the .asc files from
mris_convert. There is no geometry input, hence the vertex coordinates
are all set to (0,0,0).
Hope it helps!
All the best,
Anderson

I need to create a file where I have the parcellation value
(structure name) per vertex.
I've tried mris_convert --annot
/Applications/freesurfer/subjects/bert/label/lh.aparc.annot
/Applications/freesurfer/subjects/bert/surf/lh.pial parc.asc
But I get the error: ERROR: unknown file annot file type specified
for output: saida.asc
Has someone done this before?
Thanks
