Hello Vasu,.
You can use Packmol (
http://www.ime.unicamp.br/~martinez/packmol/), as
sugessted by david case.
With packmol you can add N number etanol and also N number of water.
This is my trick to use packmol :
- use protein, etanol and water file PDB wtihout hidrogen, as you will got
H with LEAP.
- you can use ethanol frcmod from amber or you can make with antechamber.
with antechamber, we got prep -file, continue with parmchk , we got
frcmod.etoh
- You should know size of the box, so we can know the volume. So we can
predict how many water molekul if the box is full.
sincerely yours,
Setyanto Tri Wahyudi
