ROCS with Grid Query

This cube performs overlay optimization between a query grid and a database (fit) molecule.

The query grid is read from the init port, and the database (fit) molecules are read from the intake port.

A series of calculated 3D similarity measures, along with the best overlaid query and fit molecule conformers, are added to the intake port record and emitted through the success port. The output fit molecule conformer is transformed to the best overlaid position.
