Re: [Freesurfer] PETSurfer and thickness data

Procedurally, you would create stacks (eg, mris_preproc) of the thickness and the PET data, then you would use one as the --y input to mri_glmfit and the other as --pvr input (in addition to your fsgd file or design matrix). The PVR is per-voxel regresssor, so it will create a design matrix for

External Email - Use Caution Dear FS community, I would like to assess how PET tracer uptake is related to thickness changes in AD patients. Is it possible to generate difference maps for both methods and run a GLM? Or would you suggest another approach? Thanks, Boris
