Hi Dimitrios,
4a) SSP EEG+MEG: fixed
4b) Modality in the projector name: done
10-11) The projectors need to be defined at the level of the channel file because they are used in the forward model. Which means that you cannot defined the projectors to apply independently to different sessions that are sharing the same channel file.
So you have to change the definition of your subject and use the option “No, use one channel file per condition”, so that you have one channel file per run.
This should ALWAYS be your configuration when processing multiple runs, because the head position is not the same in the two sessions. What you did in this protocol is incorrect, as the channel file in from the first session was overwritten by the one coming from the last file you linked to your database.
Cheers,
Francois
