I am a new user and I have made all the steps to calculate the induced activity of the alpha band with brainstorm. This approach consists in 1) the filtering of the EEG signal in the desired band; 2) rectifying and 3) averaging. This is called Temporal Spectral Evolution (described by Hari).
Then you subtract from TSE modulation, the evoked activity (frequency components of ERPs). As a result of this, you get the induced activity (non-phase).
My question is if this processing of the signal and its result, is adequate to calculate sources with sLORETA? I have tried, and sources look fine but I would like to be sure that we are not violating any assumption.
