I can precise the question, actually there are three:

1) ist the command correct?

mris_sample_parc -v -sdir subject001 rh ~/Documents/myROIfile.mgz rh.myROIfile.annot

2) I do not understand the meaning of this claimed file cma_parcellation_colors.txt

Actually this does not exist. In the Wiki (http://surfer.nmr.mgh.harvard.edu/fswiki/mris_sample_parc) it says that there was an optional arguement

-file <filename>

use <filename> as translation (default: 'cma_parcellation_colors.txt')


If I understand correctly, "translation" points ot a problem of different spaces, but the filename rather seems something like a parcellation/atlas color table?

3) The result of this problem seems to be that I cannot annotate the surface using the created annotation file. It gives this error, which i do not understand.



CTABfindAnnotation: ct was NULL
No such file or directory
CTABfindAnnotation: ct was NULL
No such file or directory
CTABfindAnnotation: ct was NULL
No such file or directory
CTABfindAnnotation: ct was NULL
No such file or directory
... etc.

Can anyone help me find the problem?

Thank you in advance!
