That's exactly it. I realized after running the avwmerge manually that it
was Seg Faulting every time. The problem was that my standard brain that i
was registering to was about 32 megs. Thus, every cope that needed to be
merged was also 32 megs, requiring about 2.5 gigs for a single avwmerge
process. We resampled the standard image so that it is now about 4 megs
and hopefully the avwmerge will only require about 1/8 of the ram it
required previously. Thanks so much for your help!
