I am fairly new to EEG research and I am unsure what the best ordering is for preprocessing data. Do you correct for baseline and filter the data before you go on with artifact rejection/correction, or the other way around?
I can imagine the former to be correct, because baseline correction and filtering makes it easier to interpret the data visually, making it easier to identify artifacts. However, if you filter the data first, some artifacts may become less severe, making it difficult to have artifact rejection be done automatically.
What are your thoughts?
