[Eeglablist] hi, i want to ask you a question

[hui.zhang]

hi

after I load the epoched data into eeglab, there is somethings strange in my data:
when i do the Plot-> Channel data(scroll), when i enter "20" in the scale text edit box, some epochs are only a piece of blue board. I can not distinguish any single channel data. And when i enter "1200" in the scale text edit box, these epoch become distinguishable.
did someone else have met the same thing? 
should i reject these epoch?

looking forward to your suggestions!

hui
