OENearestResidue OEGetNearbyResidue(const OE2DActiveSiteDisplay &disp, const OEDepict::OE2DPoint &point, double radiusscale=1.0)
Returns an OENearestResidue object that stores the residue which is depicted nearest to a given 2D display coordinates. By default, only residues that not further than a radius distance from the given point will be considered.
- The OE2DActiveSiteDisplay object of which atoms are being considered.
- Specifies the 2D display coordinates.
- The multiplier that can be used to increase or to decrease the radius around the given point to be considered. This value has to be in a range of \([0.75, 3.0]\).
If there is no residue close to the given display coordinates, then the OENearestResidue::IsValid method returns false.
