Hi Nisha,
You could also try packmol-memgen for this. Even though it was made mainly
for membrane packing, I added a flag that just solvates your system like
this:
packmol-memgen --solvate --pdb XXX.pdb --salt --saltcon XXX --salt_c X
(please check --help before)
Since it is only water and salt, it should take literally 10 seconds to
pack, and I consider only the real water volume, so shouldn't be far away
from the suggestions in the paper Matias sent before. You can also add your
ligands to the box using the workflow, if they are not supposed to start in
a bound configuration. This was added as a test function, so check your
system and if you have any problems just let me know.
Hope it helps,
