External Email - Use Caution
Hi Tim,
Case #8 is transforming between MNI152 and MNI305 spaces. MNI305 is different from fsaverage: one is a volumetric space and one is a surface space.
If you are indeed looking for a transformation between MNI152 volumetric space and fsaverage surface space, you can consider the following: https://github.com/ThomasYeoLab/CBIG/tree/master/stable_projects/registratio...

External Email - Use CautionDear list,
I have some points of interest (volume coordinates, e.g. '5.9, -27.7,
49.7') in MNI152 space. I would like to transform them to fsaverage space.
How should I do that?
To answer my own question, this seems to be explained as use case #8 on the following website (at the bottom):
https://surfer.nmr.mgh.harvard.edu/fswiki/CoordinateSystemsTo be precise, the website explains the transformation in the opposite direction, so one should use the inverse of the matrix given on the website.
