(I rerun pdb3gmx and used -q to get a *.pdb to compare to my original one). When I run genbox I get the *.top with all residues, but the *.gro is truncated. Did it several times with the same result...but no massage, that anything might be wrong (or I was too tired to see it. Will do it again tomorrow)

I'm not sure what the -q output does, but you can select the output 
format simply with the file extension, so pdb2gmx -c out.pdb. I can't 
think of a reason why genbox might truncate a molecule in a structure file.
