Dear Bruce, Thanks for you for your response. I am trying to generate an average hippocampal volume and its correlation with HAM-D score in early and late onset depression (eod vs lod). One way I tried to do it was by binarizing and concatanating the hippocampal volumes and then run mri_glmfit. But, I am stuck at glm_fit and would be grateful if you can let me know how to proceed from here. How do I run the glm_fit between eod and lod patients? Secondly, after running glm_fit how do I calculate the significance from sig.mgh?
Appreciate all your help. Thanks and regards, Sampada On Sun, Jul 10, 2016 at 7:15 PM, Bruce Fischl <fis...@nmr.mgh.harvard.edu> wrote: > Hi Sampada > > can you elaborate a bit?
