Estimate the head->mri transform from fsaverage fiducials.
A subject’s fiducials can be estimated given a Freesurfer recon-all
by transforming fsaverage fiducials using the inverse Talairach
transform, see mne.coreg.get_mni_fiducials().
strThe FreeSurfer subject name.
NoneThe path to the directory containing the FreeSurfer subjects
reconstructions. If None, defaults to the SUBJECTS_DIR environment
variable.
str | int | NoneControl verbosity of the logging output. If None, use the default
verbosity level. See the logging documentation and
