Hello,

Since 3dAutobox decides what unnecessary part of data to be dumped itself, it sometimes give us unmatched dimensions across different runs of data, though they have been collected from the same subject.
Is there any way that I can crop a certain size of the 3d+time data for every run, so that their sizes would match when I'm doing 3dVolreg later on?

Thanks in advance!
