I’m trying to plot filtered raw MEG data to figure out which channels are bad. Unfortunately, for some participants the plots show 1 second of ‘normally’ scaled data, but after that basically show the data in a very different scale. This is the case for a few participants, which makes me wonder if there is a structural setting that needs to be tweaked or if the data needs to be handled in some way before plotting the raw signal.
Does anyone know what is going on here or do you have some tips?
Not sure what’s going on here. It’s consistently present from about 1 second of the recording until the end of the file, in this participant and a couple of others. I’ve tried to filter the data in various ways and to look around online but I can’t find a reason yet.
