Dear experts,
I am using reg-feat2anat  to register my functional data from FSL to anatomical and starndard space in Freesurfer.

For some subjects the registration is bad.

I can easily fix anat2exf.register.dat. However, as specified in reg-feat2anat —help, I know that the registration failed as the func2std is incorrect, too.

Is it enough to correct anat2exf.register.dat to correctly transfer functional data from feat to the surface space or do I also need to correct func2std? It seems to me that in the next steps I am using, such as sampling the functional data to fsaverage and further calculations in the fsaverage space do not rely on func2std. Is this correct?

Cheers,
Aga
