[Eeglablist] [External] Re: Excluding channels in clean_artifacts

[Beach, Paul]

I’m anxiously awaiting the new functionality for clean_artifacts! And thanks for the suggestion, Scott. At first glance that may be a bit above my ability (namely the “copy the results back into the original dataset” bit). Is there a way to more simply save the ECG channel as a separate variable, remove it, run clean_artifacts, then append it back to the EEG structure? A simple way like this could also be applied to other functions that don’t have ‘exclude’ options (such as the fmrib plugin, which I use for pulse artifact removal).

Cheers
Paul

Paul -

While waiting for Arno to add the 'exclude channels' option, you could remove the ECG channels from the data *and save to a new dataset*, run the clean_artifacts function on the remaining data, then copy the results back into the original dataset.  This seems a kludgy solution, but not unlike what the new option will likely do, internally...

Hi EEGLAB’ers,

I’m curious whether there’s an easy way in which one might be able to exclude particular channels from clean_artifacts?

I’m interested in not applying it to ECG channels as it looks like it’s occasionally causing issues with their morphology. It doesn’t look like there’s an explicit ‘exclude’ option, such as in re-referencing or other commands.

Thanks!
