I'm not sure that there is any (easy) way to avoid this, given the way
the code in solvateBox works. But you should be able to use cpptraj to
superimpose the protein coordinates you get from your savePdb command back
to the original positions that were in protein-wt.pdb. Would that suit
your needs?
This is really a deficiency in the "nocenter" option in LEaP. I'll enter a
bugzilla note about this, but I'm not sure what the best fix is.
Thanks for the report....dac
