Dear freesurfers,

I am experimenting qdec with one of my discrete variables. Besides qdec.table.dat file, I do have a .levels file with the two levels of the variable (say level1 and level2). However, I keep getting the following error message:  

Reading discrete factor levels from config file /$SUBJECTS_DIR/qdec/meditation.levels
        level1
done.
ERROR: /$SUBJECTS_DIR/qdec/meditation.levels is invalid. Must have at least two levels.
Error loading the data table.

Is there something that I have missed in the declaration of the variable?

Thank you very much!

Sincerely,
Ye
