Hi Justin,
Thanks a lot!
Things worked.
Now I, however, have a different problem in extension to what I am doing.
I was able to created a sphere of water and methanol around a
polypeptide and 1 Li+ ion.
editconf -f 1li.gro -c -box 12 12 12 -o onlyli.gro
genbox -cp onlyli.gro -cs mix.gro -shell 3 -o li_sol.gro
genbox -cp li_sol.gro -cs mix.gro -shell 3 -o 6nmshell.gro
editconf -f his20.gro -d 0 -o onlyhis.gro
editconf -f onlyhis.gro -c -box 12 12 12 -o hisinbox.gro
genbox -cp hisinbox.gro -cs 6nmshell.gro -o 6sys.gro
Now I need to add few more Li ions and anions in the sphere.
I tried doing that,
genbox -cp 6sys.gro -ci 1dhb.gro -nmol 20 -o added_dhb.gro -p topol.top
(1dhb.gro is 2,5-dihydrobenzoic acid anion)
But, since the sphere 6sys.gro is essentially in a box, the dhb anions
...some got randomly placed inside the sphere and some in the open
spaces of the box in which 6sys.gro is sitting.
How can I place all the anions and then Li+ ions specifically inside the
sphere?
That's what genion is for.
