Hi Maria

The SUBJECTS_DIR is one directory above the my_subj_name. Sorry if this is a trivial point, but worth a check.

can you give me the output of following commands

echo $SUBJECTS_DIR ls $SUBJECTS_DIR

Hi all! I have some problems to visualize surfaces by tksurfer. When I try to load a surface with the command tksurfer my_subj_name lh inflated I receive the following error: ERROR: could not read header info from T1 or orig in homes/..../my_subj_name/mri The SUBJECTS_DIR is the correct one and in my mri folder there are both T1.mgz and orig.mgz. Any suggestion? Could the headers of those files be corrupted? How can I check it? Thanks in advance for any help! Maria
