Dear Users,

May I know after do the command
genbox -cp prot_box.gro -ci solvent.gro -nmol 2000 -cs spc216.gro -p
control.top -o prot_mix_sol.gro
the result shows,

Output configuration contains 1121788 atoms in 367835 residues
Volume                 :     11420.4 (nm^3)
Density                :     1007.84 (g/l)
Number of SOL molecules:  365793

I need to put the solvent mix with water with ratio approximately 80%
of solvent : 20% water.

>From here after i done the calculation its only give 5% of solvent in water.
Therefore my question is,can i add another -nmol of solvent without
insert the -cs anymore?
Hope you guys already facing the same problem like i do.
