Hi Sampada
why not just take the volume of the hippocampus from the aseg.stats? Why
do you want an mgz? You just want one number per subject, right?

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

Hi Sampada
can you elaborate a bit? What are you trying to achieve? Do you
want an
average hippocampus? Average maps of subfields? What hypothesis
are you
trying to test? The individual subject data is not resampled to
a common
coordinate system, so just averaging them as is won't produce
anything
interested.
cheers
