Parameters ---------- subjects_dir : str | None The path to use as the subjects directory in the MNE-Python config file. None will use the existing config variable (i.e., will not change anything), and if it does not exist, will use ``~/mne_data/MNE-fsaverage-data``. %(verbose)s Returns ------- fs_dir : str The fsaverage directory. (essentially ``subjects_dir + '/fsaverage'``). Notes ----- This function is designed to provide 1. All modern (Freesurfer 6) fsaverage subject files 2. All MNE fsaverage parcellations 3. fsaverage head surface, fiducials, head<->MRI trans, 1- and 3-layer BEMs (and surfaces) This function will compare the contents of ``subjects_dir/fsaverage`` to the ones provided in the remote zip file. If any are missing, the zip file is downloaded and files are updated. No files will be overwritten. .. versionadded:: 0.18 Z fsaverageTexist_okzroot.txtz'https://osf.io/3bxqt/download?version=2Z 5133fe92b7b8f03ae19219d5f46e4177)Z manifest_pathZ destinationurlhash_zbem.txtz'https://osf.io/7ve8g/download?version=4Z b31509cdcf7908af6a83dc5ee8f49fb1) _set_montage_coreg_pathopabspath expanduserjoinosmakedirsrFSAVERAGE_MANIFEST_PATH) subjects_dirrZfs_dirr[/var/www/html/bwave/python/venv/lib/python3.8/site-packages/mne/datasets/_fsaverage/base.pyfetch_fsaverages"5    rcCs>t|dd}|dkr:tddd}t|d}tj|dd|S)NFZ raise_errorZMNE_DATAzmontage coregistrationzMNE-fsaverage-dataTr )rrrrrr)rrrr_get_create_subjects_dirVs    rcCs*t|}tddd}|dkr&td||S)aSet a subject directory suitable for montage(-only) coregistration. Parameters ---------- subjects_dir : str | None The path to use as the subjects directory in the MNE-Python config file.

See Also -------- mne.datasets.fetch_fsaverage mne.get_config mne.set_config Notes ----- If you plan to only do EEG-montage based coregistrations with fsaverage without any MRI warping, this function can facilitate the process. Essentially it sets the default value for ``subjects_dir`` in MNE functions to be ``~/mne_data/MNE-fsaverage-data`` (assuming it has not already been set to some other value). .. versionadded:: 0.18 NFrZ SUBJECTS_DIR)rrr)rZold_subjects_dirrrrr _s   r )N)N)ros.pathpathrutilsrrrrrdirname__file__rrrr rrrrs  G
