Thank you very much for the information!
I am still wondering what I should do for this specific case:
I have fMRI volumes in the MNI152NLin2009cAsym space, and want to use nilearn.surface.vol_to_surf with the surface “fsaverage5” to extract the cortical activations. But from my understanding, the volume and the surface have to be in the same space, so that the surface can match those cortical voxels.
I am currently using fsaverage5[‘pial_left’] (and fsaverage5[‘pial_right’]) for this purpose. I wonder if this is correct? And I will also appreciate it if you can give me some general suggestions on this topic.
Thanks again.
