Would there be any bad consequences if I interpolate first and then run the ICA over the entire interpolated trial(s)? The reason I am asking this question is that I would like to visually inspect my data first and remove bad channels or trials (if any) prior to ICA. If the artifact is not interpolated, it is really difficult to run visual inspection or metrics on the data..
