Generating Structures
Three-dimensional structures are generated for a mapping by:
- Creating an initial set of coordinates by embedding the updated
bounds matrix for each mapping [Crippen1981]
- Cleaning up the embedded structures using the Universal Force
Field (UFF).[Rappe1992, Casewit1992] The
optimization is done with constraints to ensure that the final
structure still satisfies the pharmacophore.
- Aligning the cleaned conformation to the reference pharmacophore.[Heisterberg1990]
Whenever possible, multiple aligned conformations are generated for
each mapping. This provides the user with an overview of the ways in
which the probe molecule can satisfy the pharmacophore.<>
