mne.write_head_bem(fname, rr, tris, on_defects='raise', overwrite=False, verbose=None)[source]

Write a head surface to a fiff file.


Filename to write.

rrarray, shape (n_vertices, 3)

Coordinate points in the MRI coordinate system.

trisndarray of int, shape (n_tris, 3)

Triangulation (each line contains indices for three points which together form a face).

on_defects‘raise’ | ‘warn’ | ‘ignore’

What to do if the surface is found to have topological defects. Can be 'raise' (default) to raise an error, 'warn' to emit a warning, or 'ignore' to ignore when one or more defects are found. Note that a lot of computations in MNE-Python assume the surfaces to be topologically correct, topological defects may still make other computations (e.g., mne.make_bem_model and mne.make_bem_solution) fail irrespective of this parameter.


If True (default False), overwrite the destination file if it exists.

verbosebool | str | int | 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.
