Thanks!
That's a great idea... very clever solution!
I will work on that later in the day, if I have any trouble I will post again to this thread. I appreciate the troubleshooting help.
I guess then there isn't a way to do this more directly with 3dDeconvolve... It would be a very helpful option as datasets are getting larger and larger, and studies are now not only multi-run but are begining to span multiple sessions... could I add a feature like this to a very early Christmas Wish list?
