Running plotting with brain maps no longer works since move to kymata-core

I don't understand where it is getting /kymata-toolbox/kymata-toolbox-data from! It specifically says: "Data root set at /Users/administration/Github/kymata-core/kymata-core-data". And it is nowhere in the code. It must be an environmental flag somewhere?

OK, it is stored in $HOME/.mne/mne-python.json - @caiw can we talk about if this is a good idea?

{
"MNE_BROWSE_RAW_SIZE": "8.0,8.0",
"MNE_DATASETS_SAMPLE_PATH": "/Users/administration/mne_data",
"SUBJECTS_DIR": "/Users/administration/Github/kymata-toolbox/kymata-toolbox-data/tutorial_nkg_data/fsaverage"
}

Hah, I just got this error too.

I think using SUBJECTS_DIR may be a requirement of MNE if we want to use MNE for plotting... but where is that config file created? We didn't do it...
