[gmx-users] Confusion Regarding Vacuum

[csreddy at ncbs.res.in]

Dear All,
I am a bit confused regarding  Vacuum. I wanted to do EM in Vacuum. I
think I can proceed either of the below...

1) I create a box (editconf) and place a molecule with out solvent.
2) Never create a box, then proceed other steps as usual like EM etc.

Can we call 2nd option also a vacuum and what is more appropriate?
