Dear Amir,
This has to do with the fact that this particular view is intended for
scrolling through the whole trial (or through the whole continuous
file so the channels are spaced in such a way that it would be
possible to scroll and see the data without repositioning them. In
your case only part of the trial is displayed and if you look at the
bottom of the window you'll see that at the end of this trial (which
is not displayed) there is increase in the GFP (probably due to an
artefact) and that is the likely reason why it's displayed like that.
I suggest that for reviewing artefacts you switch to scalp view
(toggle button at the top) which is more convenient for that. Also
there are automatic (artefact button) and semi-automatic (Fieldtrip-
based function in MEEGtools) tools that you could use for that and it
could probably save you some time. Robust averaging of time-frequency
images is also something you might want to consider.
Best,
Vladimir
