OEOmegaSampling

This namespace contains constants that are used with OEOmegaOptions to control the defaults to be set for omega options. Different sets of default options prepares omega to generate structures that are optimal for different usages.

Classic

Options to generate a set of conformers representing a gas phase ensemble.

Dense

Options to generate a dense set of conformers optimal for FreeFormConf usage.

Warning

GPU-Omega is not compatible with the dense mode default force field. To enable GPU-Omega and utilize a GPU set OETorDriveOptions::SetForceField to OEMMFFSheffieldFFType::MMFF94Smod_NOESTAT

Pose

Options to generate a set of conformers suitable for molecular alignment and pose prediction by docking.

ROCS

Options to generate a set of conformers suitable for ROCS usage.

FastROCS

Options to generate a sparse set of conformers suitable for FastROCS usage.
