Dear everyone,
I have a very basic question (I am sorry if this is a duplicate question, but I was not able to find any similar question). For a behavioral task I let participants practice for one run or more (it is variable) before the actual task starts. What is the best way to define practice trials in bids? I have not found any specific case covered in the bids website (I might have missed it though). Should the practice run be defined as a separate session, or should it rather be defined as an extra run for which I specify a different acquisition label (e.g. acq-practice)?
I hope I explained the issue clearly enough.
Thanks a lot.
Emanuele
