I do still have a question regarding the censor file in regression. I notice that, by default, it censored the high motion volume (based on enorm) and one volume before. Is there any reference for doing this? I mean like why high motion volume plus one BEFORE, but not both BEFORE and AFTER? I know 1d_tool.py can add AFTER as well, but just want to check in if there is a reference that I can cite on this issue. Thanks!
