My question is if the re-reference step must be done before epoch the data and artefact removal. Because I want to do all of preprocessing steps and artefact removal, and then apply several different re-reference selections, by this way I don’t need to do all of preprocessing steps again. Does it sound fine? Is there any other artefacts or problems that will be induced by the re-reference of last step.</div><div class=""><br class=""></div><div class="">I am looking forward your any advices<br class=""><br class=""></div><div class="">Thank you in advance,<br class=""><br class=""></div><div class="">Bin</div><div class=""><br class=""></div><div apple-content-edited="true" class="">
