Magnetoencephalography (MEG) power topography may be useful for obtaining
discriminative brain activity patterns that can distinguish depressed patients from healthy
control subjects at the individual level. However, the application is still limited due to the lack
of adequate analysis strategies to remove artifacts from the MEG signals. In this study, the
multichannel matching pursuit (MMP) method was designed; in this technique, a linear
decomposition method that provides components by iteratively reanalysing a residual signal …
