Hello,
I intend to generate a stack of molecules with the command line:
genconf -f Hexane.gro -nbox 8 6 4 -o Hexane-STACK.gro
Hexane.gro has box size of 3*3*3 nm3 and I need to have about 7 molecules
per nm^3. So I multiplied 7 by 27 (box size) to get (7*27=)189 molecuels.
What I get from the above command is (-nbox 8 6 4 )192 but the system size
in getting bigger as well!. * 24.00000 18.00000 12.00000 nm^3.*
Could you dear experts guide me how I can reach the system density I want.
Also to I wanted to know what is best value -dist option. Is it ok if I
leave the distance between boxes 0 0 0?
Thank you,
Hexane-STACK.gro:
Glycine aRginine prOline Methionine Alanine Cystine Serine
