Dear Nima,

Here is a question for you about the PREP pipeline. Would you mind helping

> (ii)If I truely ignoring boundary events and run PREP, is there any problem?
> (iii)If I do not merge dataset and use datasets of single block, it will very likely lead to inconsistent number of channels in dataset of subject level due to different number of bad channels, and that will not be legitimate in the downstream behavior like ICA.
