What are 'pb.' files?

Hi,

I am using afni_proc.py for preprocessing. In addition to the output files that I am interested in, this method generates many intermediate files that can take up a lot of space, for example those starting with “pb.” What are these files and how do I know whether I need them (what might someone need them for)?
I found evidence of their acknowledged existence in the help files, but not a specific list of what they are and what they are for.

Thanks,
Priya

Those are the output for each “processing block” . The number can vary depending on which processing blocks you have requested and the order.

Hi, Priya-

There are some educational resources you can browse about AFNI in general and afni_proc.py specifically, located here:

There are some particular AFNI Bootcamp recordings here:

and here:
