mne_label_ssp
Overview
mne_label_ssp creates SSP (Signal Space Projection) projectors from cortical label ROIs. Given a forward solution and one or more FreeSurfer label files, it extracts the forward model columns corresponding to each label's vertices, computes the SVD, and creates projection vectors that suppress activity from those regions.
This is a C++ port of the original MNE-C tool by Matti Hämäläinen.
Usage
mne_label_ssp [options]

Example
# Create SSP projectors from two label ROIs
mne_label_ssp --fwd sam-meg-fwd.fif \
--label lh.V1.label --label rh.V1.label \
