Hi Markus,

maybe for some weird reason it uses the subjects_dir from the environment variable instead of the qdec file (that would probably be a bug). If that's the case, try setting the subject dir on the command line before starting qdec:
setenv SUBJECTS_DIR ~/Documents/ARNAUD/
(or the full path). If you use a bash shell, use the equivalent export command for that.

Best, Martin

Dear all,

I am trying to make work Qdec on my system ubuntu 12.04.

freesurfer-Linux-centos4_x86_64-stable-pub-v5.3.0

After I have loaded my qdec.table.dat and renamed the analysis folder , when I then try to create the "stats tables", I get an error and it blocks at 20% of the waiting bar.


Data table loading completed successfully.
SUBJECTS_DIR is '~/Documents/ARNAUD/'

    while executing
"vtkTemp2 GenerateStatsDataTables"

It seems that it tries to write into the default SUBJECT_DIR, thing that I do not understand as I put the actual SUBJECT_DIR in the top line of qdec.table.dat (and it is correctly recognized in the qdec window SUBJECTS_DIR).

How could I come around that problem?

Thanks in advance!
Markus
