Thanks for responding on a holiday! Happy Thanksgiving! We cracked it - the psfgen wasn't totally error free. I'm not sure why it generated a psf file anyway, but when we fixed the errors in residue numbering [wrong numbers left over from a previous run with almost but not quite the same structure], it solvated. It took piping the psfgen messages to a file so we could conveniently look at everything to locate the problem.
Thanks again!
