Dear Rick,
thank you very much for this fast and clear response, now I understand.
One related question:
It seems that when using the default otions, uber_subject.py creates a script that censors the TR exceeding the threshold plus the previous TR. I don't understand why I should censor the previous TR - I thought there are rather effects of motion on the following TRs from what I read. Is it very strongly recommended to censor the previous TR as well or would it be valid to only censor the one exceeding threshold?
Best,
Janina
