Detecting bad segments or bad channels

[monaghaheri]

Hi Francois,
Thanks for responding and helping me. I understood that there are 2 solution:

1. With out marking bad segments, running ICA in order to capture some artifacts as an independent components;
2. Concatenating good segments ( or marking good segments) and run ICA on these parts.

So then, could you please explain me your reply in other discussion?( because I thought it was against what I understood)

Bad segment removing

This is correct. Mark the breaks as bad segments and they will be ignored from the ICA and SSP computations. To double-check the bad segments are excluded: mark as bad also the rest of the recordings, so that the entire file is marked with overlapping bad segments. Run the SSP or ICA process, it should return an error saying that no good data could be read from the input file.

With regards
Mona
