Hello!

I would like to know how to calculate the number of water molecules to be
able to use SPLIT. In the example (
http://archive.ambermd.org/202002/0194.html) they state that: Water box 12Å
=> Nw ~ 7000 molecules

In my particular case tleap returns the following.

solvateoct solvcomplex TIP3PBOX 12.0
Scaling up box by a factor of 1.201123 to meet diagonal cut criterion
  Solute vdw bounding box: 38.539 80.427 50.856
  Total bounding box for atom centers: 109.253 109.253 109.253
      (box expansion for 'iso' is 122.4%)
  Solvent unit box: 18.774 18.774 18.774
  Volume: 670111.666 A^3 (oct)
  Total mass 368010.690 amu, Density 0.912 g/cc
  Added 18555 residues.

Thanks
