mne.bem.make_flash_bem

mne.bem.make_flash_bem(subject, overwrite=False, show=True, subjects_dir=None, flash_path=None, copy=False, verbose=None)

Create 3-Layer BEM model from prepared flash MRI images.

Parameters

subjectstr

Subject name.

overwritebool

Write over existing .surf files in bem folder.

showbool

Show surfaces to visually inspect all three BEM surfaces (recommended).

subjects_dirstr | pathlib.Path | None

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

flash_pathstr | None

Path to the flash images. If None (default), mri/flash/parameter_maps within the subject reconstruction is used.

New in version 0.13.0.

copybool

If True (default False), use copies instead of symlinks for surfaces (if they do not already exist).

New in version 0.18.

verbosebool | str | int | None

Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Notes

This program assumes that FreeSurfer is installed and sourced properly.

This function extracts the BEM surfaces (outer skull, inner skull, and outer skin) from multiecho FLASH MRI data with spin angles of 5 and 30 degrees, in mgz format.
