Greetings VMD,

Please add this to your script library.

Here's a script I wrote that addes Na+ and Cl- to a system that already has
water. I said in JBSD v22n6 2005 that I'll make it freely available so here
it is.

It does not neutralize the system but merely replaces random waters with Na+
and Cl- so that the effective excess ion concentration is 150mM NaCl.

(if you have a charged system such as DNA you'll still need to add
neutralizing ions. there's already a tool from that does this)

Happy VMDing.
