Hello FreeSurfer Experts,

I am trying to run QDEC for a group comparison study. I am following the tutorial found on http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QdecGroupAnalysis_freeview

However, when I try to load my data table it returns the error.

----------------------------------------------------
Loading data table /home/pcopy_project/qdec/qdec.table.dat...
Number of columns:  5
fsid column:        1
Number of factors:  4
Number of subjects: 57
Reading discrete factor levels from config file /home/pcopy_project/qdec/gender.levels
    Female
    Male
done.
Reading discrete factor levels from config file /home/pcopy_project/qdec/diagnosis.levels
    Control

    Disease

done.

ERROR: Subject SIYA_001 has an invalid level 'Male' in the gender column
INFO: If 'gender' is a discrete factor, then create a file
named 'gender.levels' containing the valid factor names
one per line.
Error loading the data table.
--------------------------------------------------------

As you see I have a 'gender.levels' file in the same directory as the data file and it reads it above. I still get the error.

I am new to QDEC and any help would be appreciated.

Thank you
