[gmx-users] editconf -density

[Dan Sponseller]

You do not state your original density. But lets say you need to reduce volume 3% to get your correct density. Use:
ediftconf -f solv_large.gro -o solv_large_scaled.gro -scale 1 1 0.97

Just do a quick side calculation for what you need and substitute in for 0.97.
