Re: [Freesurfer] mri_glmfit with pvr

You need to include elements for the PVR regressors in your contrast. I see that you only have four elements in the examples below and four classes, so you will need to add more On 6/9/2021 10:38 AM, std...@virgilio.it wrote: External Email - Use Caution Thanks If I have 4 groups G

Hi Aga, what you have done is correct, no need to include the pvr in the fsgd. doug Burzynska, Aga wrote: > Dear all, > I am trying to make group level analysis of functional data on the surface > and add per-vertex regressors (PVR, here: cortical thickness) into the > design. When I view the r

[Freesurfer] mri_glmfit with pvr: how to include pvr in the fsgd file?

Dear all, I am trying to make group level analysis of functional data on the surface and add per-vertex regressors (PVR, here: cortical thickness) into the design. When I view the results I have the feeling that the PVR is not really included in the model: I am using the command: mri_glmfit --
