mne.head_to_mri

mne.head_to_mri(pos, subject, mri_head_t, subjects_dir=None, verbose=None)

Convert pos from head coordinate system to MRI ones.

This function converts to MRI RAS coordinates and not to surface RAS.

Parameters

posarray, shape (n_pos, 3)

The coordinates (in m) in head coordinate system.

subjectstr

The FreeSurfer subject name.

mri_head_tinstance of Transform

MRI<->Head coordinate transformation.

subjects_dirstr | None

The path to the FreeSurfer subjects reconstructions. It corresponds to FreeSurfer environment variable SUBJECTS_DIR.

verbosebool, str, int, or None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.

Returns

coordinatesarray, shape (n_pos, 3)

The MRI RAS coordinates (in mm) of pos.

Notes

This function requires nibabel.
