Re: [Freesurfer] qdec

Hi Julia, qdec cannot handle 3 levels. You'll have to use the command-line stream (ie, creating your own fsgd and contrasts and running mris_preproc, mris_surf2surf, and mri_glmfit). doug

Dear freesurfer experts,

I am trying to run a volume analysis with qdec. One of my discrete variables has 3 three levels...Is Freesurfer capable of creating a FSGD file of a discrete variable like this?

When I m running the analysis, the terminal also says "no contrasts specified" after trying to read the source surface. What is wrong here?

Thank you all so much for your help,

Julia
