We don't use MNI152 much. We have an affine matrix to convert from 305 to 152, and that 152 is the one in FSL

Dear FreeSurfer developers,

Which MNI152 space is used within FreeSurfer? Is it the MNI152 nonlinear 6-th generation (as in, for example, FSL), or another one, like MNI152 nonlinear 2009a, 2009b or 2009c?

I wasn’t able to find this information in the fswiki.

I checked https://surfer.nmr.mgh.harvard.edu/fswiki/CoordinateSystems and the documentation of certain functions, such as mri_cvs_register.

Thank you for your help!

All the best,

Inês Pereira
