swin — APBS-PDB2PQR 1.6 documentation

# swin

Specify the size of the support (i.e., the rate of change) for spline-based surface definitions (see srfm (elec)). The syntax is:

    swin {win}

where `win` is a floating point number for the spline window width (in Å). Usually 0.3 Å.</p> Note that, per the analysis of Nina, Im, and Roux (article)</a>, the force field parameters (radii) generally need to be adjusted if the spline window is changed.
