Hi Doug,

Thanks, I see. That really helps a lot. I will try to use the command line 
version.

Best,
Daniel

sorry, you cannot have three levels in qdec (two max). You will need to use the 
"command line" stream (ie, create a FSGD file and consrast files, run 
mris_preproc, mri_surf2surf to smooth, mri_glmfit, and mri_glmfit-sim). See the 
wiki for more details.

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
