Can you point me in the direction of where your team has answered what I think must be a common question:
how do you handle registration/normalization if someone gets out of the scanner and then back in?
Meaning--subject does structural scan and 3 runs of fMRI task; has to get out to use bathroom; gets back in to finish other 3 runs and we do a 2nd structural scan just to have it.
When I preprocess data with afni_proc.py--how do I handle fact that they got out of the scanner (clearly moved for runs 4-6 vs runs 1-3)?
Not sure if (a) using the giant move option takes care of this with the original structural scan?
Or (b) if I need to first register runs 1-3 with structural scan #1, register run 4-6 with structural scan #2, and then concatenate?
If (b)--how?
Naively--feel like you must have answered this in handouts somewhere or on the message board--b/c it is a common occurrence.
Tnx!
