no, I haven't seen that before. Can you cat /home/virtualuser/freesurfer/subjects/linziyi/mri/transforms/talairach.xfm

and send us the contents?

Hi All,

Sorry to take up your time.

My freesurfer now can not recognize the re-con files (such as the .mgz
files, or .xfm files, etc). 
For example, I run this command to check the talairach transform:
tkregister2 --mgz --s linziyi --fstal --surf orig
The terminal then reports:
ERROR:
/home/virtualuser/freesurfer/subjects/linziyi/mri/transforms/talairach.xfm
does not start as 'MNI Transform File
This file talairach.xfm does exist. But under Xubuntu, this
talairach.auto.xfm file has a different icon and appears as "executable
file". That's quite strange because I did not make such change to it.

These files did work when I just finished the re-con. But afer the re-con, I
moved them from the freesurfer subjects folder to the shared folder (shard
with XP), because the freesurfer subjects folder has a limited space. After
a few days, I moved them back to the subjects folder for doing the
statistical analysis, and then I have such problem. Even under the shared
folder, the files can not be read either.

For the cases I just re-con, since they are not moved to elsewhere,
everything seems OK.

Have you guys had such problem before and how to fix it? Thanks!
