create_eog_epochs Finds Alpha in Resting State Analyses

Hi all,

   Using create_eog_epochs during resting state analyses, I keep having the algorithm lock on to alpha, usually from the occipital region. Does anyone have suggestions for how to avoid this?

Thanks,

You should be able to change the filtering parameters and/or EOG channel
used to avoid this.

Thanks for the advice!

I don't really have extra EOG channels, one generally catches most of the blinks and the other most of the saccades but I'll try moving the high pass down to avoid people whose alpha is low frequency.
