Hello All,

I have a very simple qdec question.

I have three groups (relatively age and sex matched), each grp has 8 subjects. I have created a qdec.table.dat file with contents as follows

SUBJECT_DIR /jet/rito/freesurfer_data/ fsid gender age diagnosis 01 Female 40 Group1 02 Female 32 Group1 03 Female 41 Group1 04 Female 33 Group1 05 Female 36 Group1 06 Female 37 Group1 07 Male 49 Group1 08 Male 46 Group1 09 Male 37 Group2 10 Female 38 Group2 11 Male 38 Group2 12 Female 32 Group2 13 Female 32 Group2 14 Female 45 Group2 15 Female 31 Group2 16 Female 45 Group2 17 Female 32 Group3 18 Female 40 Group3 19 Male 45 Group3 20 Female 32 Group3 21 Male 31 Group3 22 Female 30 Group3 23 Female 32 Group3 24 Female 36 Group3

I have also created two discrete factors.level files,

gender.level Female Male

diagnosis.level Group1 Group2 Group3

When I try to load the qdec.table.dat file, I get an error -

/jet/rito/freesurfer_data/qdec$ Loading data table qdec.table.dat... Setting SUBJECTS_DIR to /jet/rito/freesurfer_data/ Number of columns: 4 fsid column: 1 Number of factors: 3 Number of subjects: 24

Data table qdec.table.dat loaded. SUBJECTS_DIR is '/jet/rito/freesurfer_data/' sh: Syntax error: Bad fd number ERROR: QdecProject::VerifySubjects: Couldn't find subject '1' in SUBJECTS_DIR sh: Syntax error: Bad fd number ERROR: QdecProject::VerifySubjects: Couldn't find subject '2' in SUBJECTS_DIR sh: Syntax error: Bad fd number

etc

Can you tell me what am I doing wrong ?

Thanks

Ri
