Microsolvation Builder
**********************

The Microsolvation Builder allows you to add a sphere of solvent
molecules around your molecular system.


How to use the microsolvation builder
=====================================

1. **Select the Solvent**: choose from the list of available solvents.

2. **Adjust the radius of the solvent sphere**: use the slider to
   change the radius of the solvent sphere. The number of solvent
   molecules that will be added is displayed at the bottom of the
   panel.

3. **Change the solute factor**: use the slider to change the solute
   factor to control how close solvent molecules can get to the solute
   (your existing molecular system). A solvent molecule will only be
   added if its atoms are not too close to any atoms in your solute,
   based on a distance calculation that includes the sum of atomic
   radii multiplied by this factor. The number of solvent molecules
   that will be added is displayed at the bottom of the panel.

4. **Generate Molecules**: click the 'Generate Molecules' button to
   add the solvent molecules to your system.

5. **Finalize**: use **Close** to accept and close the builder, or
   **Cancel** to discard it.

The solvent molecules will be positioned around either the center of
your current selection or the center of mass of the entire molecular
system if there is no selection.

The geometry of the added solvent molecules is based on data from MD
(molecular dynamics) calculations and is not be optimized for proper
interactions with your specific molecule.

If you add Water, all added water molecules will be identical (good to
use as fragments). If you add Chloroform or Methanol, the added
molecules will not be identical.
