srad¶
Note
Some versions of this command have been ported to the new APBS syntax (see YAML- and JSON-format input files):
- Nonpolar calculations: see
nonpolar.Nonpolar.solvent_radius()
for more information. - Finite-difference Poisson-Boltzmann calculations: see
finite_difference.FiniteDifference.solvent_radius()
for more information.
This keyword specifies the radius of the solvent molecules; this parameter is used to define various solvent-related surfaces and volumes (see srfm (elec)). This value is usually set to 1.4 Å for a water-like molecular surface and set to 0 Å for a van der Waals surface. The syntax is:
srad {radius}
where radius
is the floating point value of the solvent radius (in Å).
This keyword is ignored for srfm spl2
(see srfm (elec)).
