Dear Dr. Spielberg,

thank you very much for your helpful responses and also for the mask script! I also do all the preprocessing in SPM - is there any obstacle using the mask script apart from having to convert the .nii files to .nii.gz files? (Maybe Jeff is referring to this question with his comment on the "scrubbing option", which I don't understand?)
I'd also be very grateful for the concatenation script. I'm glad I could help with the filenaming question.

Best, Hannah
