Hi ndr, yes indeed that is possible. Check the link below. TDT: Decoding having only one run - #6 by Tamer_Gezici
You will need to modify your cfg.files.chunk to do that, my example is not entirely suitable for your case. You’ll need to modify things based on your study/design.
Currently, to me it is unclear if you want to leave one beta and classify within a run, or across runs as well.
Hope this helps.
