Dear Doug

Thanks a lot for your reply.

So, how can I solve this issue?

Subject: Re: [Freesurfer] mri_glmfit --no-prune

The ces stack has had the medial wall  masked out so all the values there are 0. When you specify --wls, it normalizes the weights across subject. However, in the medial wall, all the weights are 0 (can't divide by 0, so it throws an error.

Hi Freesurferers

I am running mri_glmfit on a group data using --no-prune flag. i 'm getting the below error. 

I appreciate if you could let me know what the issue is.
