I have 3T, T1- weighted, MR images of marmoset brain. I have segmented these images into GM, WM and CSF (using SPM). My aim is to calculate the cortical thickness and the brain compartment's volumes to study the changes that occur through aging.

I have looked into softwares like FeeSurfer for the cortical thickness and the GM,WM volume calculations, but all these softwares are not adapted to be used on non-human images (since they are based on human brain atlases). Specifically, I could not figure out if I could define the marmoset Atlas in FreeSurfer and further use the software.

For this, I would appreciate any help concerning a direct method or any software (I might not be aware of) that will help me do my calculations.

Thank You.
