Hi Matt,
density is really just average gray matter per unit volume. Why would you want to compute such a thing? I think the way SPM/FSL does it is to take a binary segmentation and smooth it, but you can check with them.

Hi Freesurfer Experts,
I have been running Freesurfer to calculate the grey matter volume of pediatric brains but I was wondering if there was a method to determine grey matter density using Freesurfer? I have read a question previously posted asking a similar question, but there had been no replies or answers. If there is no command to calculate the density of grey matter, is there any alternate method to determine the density from the volume data?
Thanks,
Matt
