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

[Toby Fernsler]

Hi Hui,
The "blueout" you see is due to a high level of variance relative to the
variance we expected. It is a scale-dependent effect and may not mean
your data is bad, just that the scaling is different. I would suggest
you adjust the scaling until you can see the data clearly, and compare
epochs within the dataset to identify ones that should be removed.
