The whole dataset ~20 ppts have the strong noise in, however only a few have no alpha peak. I will keep investigating - a massive amount of overhead goes into collecting this dataset, with limited opportunity to recollect. Thanks so much for all your help! Its really appreciated, and has helped rule quite a few things out

I’m glad I could help a little. If anyone else has ideas (or has seen similar EEG data before), please feel free to chime in!
