Simulate Your Own Data in MNE
You can use the MNE function mne_simu to produce your own EEG or MEG data, for different ROIs (Labels). You can then apply your Inverse Operator to these data, and check how well activation from these areas are localised. In order to use mne_simu, you need a forward solution created in MNE (e.g. from a real measurement). For more details, please refer to the MNE manual (V2.6, V 2.7).
Example:
mne_simu --meg \
--fwd ${path}/${subjects[m]}_5-1L-MEG-fwd.fif \
--label ${STCpath}/Label_Occ-lh.label \
--label ${STCpath}/Label_Cent-lh.label \
--label ${STCpath}/Label_Ins-lh.label \
--out ${STCpath}/PubLabel-lh.fif---
