Voxel-Based Morphometry

Hi AFNI expert,
is it still not possible to performed VBM with AFNI?
https://afni.nimh.nih.gov/afni/community/board/read.php?1,70296,70303#msg-70303

if not, can I use (SPM, ANTS, or something else) to calculate the voxel-wise volume ratio changes after using @animal_warper?
Thanks a lot!
Clément

Try 3dNwarpFuncs. I’m no expert on VBM, but the -bulk option gives you the Jacobian information that I think you want. Warps that are composed similarly by other packages should work the same as long as they are dx,dy,dz volumes.

Thank you so much Daniel!
