Re: [Freesurfer] glmfit for paired-diff on 2 groups

hi doug Thanks for checking my code and the hint with the smoothing rate. I appreciate your time on my issue. I’ve ran a series of different smoothing rates (from 10-30mm) and 25mm showed the best results for our data in terms of cluster size but still prominent effects in summary statistics.

Yes, that looks correct, though I could be more confident if you send the command lines used and your fsgd file(s). doug On 10/31/2013 07:32 AM, Vivian R. Steiger wrote: > Dear FS-Experts, > > I would like to compare 2 Groups (Responder (N=19) vs. Non-Responder (N=11)) > with longitudinal dat

Dear FS-Experts, I would like to compare 2 Groups (Responder (N=19) vs. Non-Responder (N=11)) with longitudinal data. Participants from both groups had only 2 scan sessions in each case 10 weeks apart. So far is used the glmfit-variant with --paired-diff option in the first place. (based on ht
