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_dirpath-like | None

The path to the directory containing the FreeSurfer subjects reconstructions. If None, defaults to the SUBJECTS_DIR environment variable.

Returns:

coordinatesarray, shape (n_pos, 3)

The MRI RAS coordinates (in mm) of pos.
