[Eeglablist] Conducting ICA on correct or all epochs

Hi everyone,

I am running a simple EEG experiment where I measure reaction times and
accuracies.

I want to use ICs for artifact removal, and I will report only the correct
trials (hits).

So would it be better to use the correct epochs for the ICA to correct for
the artifacts or is it OK to use all the epochs to detect the artifacts and
then run the artifact correction (pop_subcomp) followed by deleting the
incorrect epochs?

Thanks,
Baris
