Hi,

I'm getting an error from refmac that I can't quite decipher, and I was
wondering if someone could help me out? The error message is appended below. For
what it's worth, I've previously run this job and not had any problems. This is
simply my next iteration in refinement, so the pdb is essentially the same as
those I used previously, but with a few more aa's added. It seems to be
complaining of too many chains, but I only have three...

Thanks for any suggestions!
