[Eeglablist] STUDY clustering plotting options - ERP polarity inverting and amplitude change when reallocating to new cluster

[Makoto Miyakoshi]

Dear Joshua,

Hmm that sounds like a bug, but one IC alone in a cluster sounds already
pathological to me and anything unexpected could happen. Try to avoid it.

It would be very nice if you could file the problem to EEGLAB bugzilla.

I appreciate your cooperation and patience.

Makoto
