Oct box and ptraj

This should be an easy question for someone to answer...

I have a protein in a truncated octahedron box of water. During the md
run, iwrap=0, so the coordinates are not written out as nice pretty 'box'.
When dealing with cubic systems, I've used ptraj to center my protein and
wrap the water back into a cube. In attempting to do this with the Oct, I
get my peptide centered in the pdb output, with what I guess is the Oct
box of water hanging off to one side. I'm certain I'm doing something
wrong. I looked through the documentation for ptraj and the tutorials,
but either the answer's not there, or I need to be beaten over the head
with it (quite probably the latter). Here's the ptraj input file I was

trajin mdcrd
trajout mdcrd_wrapped
center :6

Thanks for your help.
