I want to create inverse operator so I can plot them in source location. However, I just have a raw EEG data and I donât have a structural MRI scan of the subject. As I understand, MNE provides standard source spaces with predefined locations but I couldnât make it.
Now, I want to know how I can inverse operator for my data. If there is anyone could help me with this or if there are any resources that could provide further insight, I would greatly appreciate it.
KeyError: âKey âSUBJECTS_DIRâ not found in the environment or in the the mne-python config file (C:\Users\Eng\.mne\mne-python.json). Try either os.environ[âSUBJECTS_DIRâ] = VALUE for a temporary solution, or mne.utils.set_config(âSUBJECTS_DIRâ, VALUE, set_env=True) for a permanent one. You can also set the environment variable before running python.â
Can I use the subjects that stored in mne.dataset subjects_dir=mne.datasets.sample.data_path() / "subjects"
