[Eeglablist] EEGLAB - Merge Dataset of Continuous Data Into a Single Continuous File for BCI Training?

[Makoto Miyakoshi]

Dear Kevin,

I agree with Michael--appending two datasets using EEGLAB will insert
'boundary' event to show that two data streams are connected at that point
where there may be discontinuity which any filter method should avoid.
