External Email - Use Caution
Dear 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):

To be precise, the website explains the transformation in the opposite direction, so one should use the inverse of the matrix given on the website.
