Thx Tzvetan for pointing to the ft_selectdata function. Unfortunately, I don't think it really does what I want it to do. I really only want to shift the time axis backwards for a certain interval per subject and not make a selection of data segments. Maybe I am getting something wrong how ft_selectdata works ...? Anyways, I already re-ran the pipeline from scratch.
Thx again, Tzvetan. Hope to see you soon again!

ft_selectdata is probably what you need.

I learned that ft_redefinetrial is only supposed to be applied on raw data (coming from ft_preprocessing). Am I correct that at this point the simplest way to shift the time axis is to write my own code (something like data2.time=data.time-0.02) rather than applying ft_redefinetrial on the raw data and calculating the TFRs again.
