Syntax: set radius {<value>}
The RasMol set radius command is used to alter the behaviour of the RasMol dots command depending upon the value of the solvent parameter. When solvent is true, the radius parameter controls whether a true Van der Waal's surface is generated by the dots command. If the value of radius is anything other than zero, that value is used as the radius of each atom instead of it true VdW value. When the value of solvent is true, this parameter determines the `probe sphere' (solvent) radius. The parameter may be given as an integer in rasmol units or containing a decimal point in Angstroms. The default value of this parameter is determined by the value of solvent and changing solvent resets radius to its new default value.
