Dear FreeSurfer creators and experts,

I am trying to run qdec with one discrete with three levels (i.e., https://surfer.nmr.mgh.harvard.edu/fswiki/Fsgdf3G0V) but there is some error message:

ERROR: no contrasts specified.

Error in Analyze: command failed: mri_glmfit --y …

I am wondering if three levels a discrete factor are currently supported in qdec in FS 5.3?

Thanks!

Daniel
