mne.head_to_mri#
- mne.head_to_mri(pos, subject, mri_head_t, subjects_dir=None, *, kind=None, unscale=False, verbose=None)[source]#
Convert pos from head coordinate system to MRI ones.
- Parameters:
- pos
array, shape (n_pos, 3) The coordinates (in m) in head coordinate system.
- subject
str The FreeSurfer subject name.
- mri_head_tinstance of
Transform MRI<->Head coordinate transformation.
- subjects_dirpath-like |
None The path to the directory containing the FreeSurfer subjects reconstructions. If
None, defaults to theSUBJECTS_DIRenvironment variable.- kind
str The MRI coordinate frame kind, can be
'ras'(default in 1.2) to use MRI RAS (scanner RAS) or'mri'(default in 1.3) for FreeSurfer surface RAS.New in version 1.2.
- unscale
bool For surrogate MRIs (e.g., scaled using
mne coreg), if True (default False), use the MRI scaling parameters to obtain points in the original/surrogate subject’s MRI space.New in version 1.2.
- verbose
bool|str|int|None Control verbosity of the logging output. If
None, use the default verbosity level. See the logging documentation andmne.verbose()for details. Should only be passed as a keyword argument.
- pos
- Returns:
- coordinates
array, shape (n_pos, 3) The MRI RAS coordinates (in mm) of pos.
- coordinates
