[gmx-users] two pdb files

[Vitaly Chaban]

Justin, Florian,
Thank you very much!

Very useful feature! I do not know why it is not listed with
 genconf -h
 in my gmx-3.3.1 but it works.

Yes, the problem was in fact in quick changing numbers. I just used
cat 1.gro 2.gro > 12.gro
and then
genconf -f 12.gro -renumber.
