Hi Mark,
I have 3 questions:
1. According to the FSL website, I ran a vertex analysis of subcortical gray matter with option --useReconMNI and another vertex analysis with --useRigidAlign and --useReconNative. However, outcomes are totally different. How can I choose the best analysis? (Registrations and segmentations were visually checked in all participants).
2. I also ran a volumetric analysis of subcortical gray matter but volumes in FSL and Freesurfer (recon-all) differed significantly. Could you explain why this happened and what I can do to get more consistent results?
3. I found significant volumetric changes of subcortical gray matter with Freesurfer but this could not be reproduced with a shape analysis in FSL. I know that a vertex wise shape analysis is different from a volumetric analysis, but I would suppose that shape analysis would show a more "specified" picture of the volumetric changes. Could you please help me to solve this problem?
Thanks in advance,
Henk-Jan
