Dear NAMD users,
if I add with the "Add Ions Extension" in VMD ions (set salt
concentration to e. g. 0.15 M / l and neutralize system)
I get ions inserted in my cell (e. g. CaCl2).
However, if I calculate the cell volume, and count the number of ions
VMD inserted in my PDB file,
I do not arrive at the same molarity as i specified, but i'm slightly
off the exact concentration.
Is this to be expected? Or am I'm doing something wrong?
