Amplitude threshold options

Hello,

When working with amplitude threshold options in "detect bad trials: peak to peak" function, I would like to establish a threshold for EEG signal of +/- 50 microvolts. However, the only option is doing it peak to peak. There is, however, another function called "detect events above threshold" which I believe may have what I want (please correct me if I am wrong), but, in that one, it forces me to chose a channel, and I would like to include all EEG channels at once. Is there a functionality that I am missing to do what I want to do?

Many thanks in advance,

Fran

No, this is indeed not possible.

Two possibilities if you really want to do this type of detection:

If you modify Brainstorm processes: Make a copy of the function in your .brainstorm/process folder, modify the file name and the comment of the process. This way it won't disappear the next time you update Brainstorm.

Many thanks! I thought on the second option but certainly the first one seems better.
