Gaussian Interface for HyperChem
The first success of the origin of the receptor subtype selectivity via quantum mechanics using core technology of ONIOM Interface for Receptor has been accepted for publication.
The most powerful and sophisticated molecular modeling environment
The most powerful computational chemistry environment
"Gaussian Interface for HyperChem" can automatically prepare a Gaussian input file, "job file", for a molecular system constructed using the powerful molecular modeling function of HyperChem. The calculation results (atomic charges and optimized structure) of the Gaussian job can be immediately reflected to the corresponding molecule in the HyperChem workspace.* The interface can prepare almost all of major methods and options except for the ONIOM method and supports the Link1 calculations of Gaussian. When a multi-step job is used, the interface can reflect these results, separately. When some molecules exist in the HyperChem workspace, the interface can treat these molecules independently or simultaneously.
Gaussian Interface for HyperChem is an add-on program to the Peripheral Modeling program of the Homology Modeling Professional for HyperChem package. Therefore, this program serves as a logical molecular modeling tool for preparing a small molecule in a biological macromolecular system, as well as can be used for obtaining the chemical properties of a simple small molecule. When the interface is used for a biological macromolecular system including some small molecules, the interface can provide a simple, high-speed, and highly precise method for preparing the atomic charges for the entire system instead of the QM/MM method such as the ONIOM method (see the advanced usages and tutorial).
Moreover, since HyperChem carries a Z-matrix interface for Mopac5, 6, and 7 in default, their Gaussian jobs can be initiated using Gaussian Interface for HyperChem without any conversions to the corresponding internal coordinate. If Q-Chem for Windows and a set of MOPAC2000 and Mopac Interface for HyperChem are available, the HyperChem - Gaussian - Mopac - Q-Chem compatibility becomes possible on the HyperChem graphical user interface, thus giving a powerful computational chemistry environment.
* When a checkpoint file name is specified in the Link0 entry box of Gaussian Interface for HyperChem, the results of the corresponding Gaussian job can be analyzed in detail, using a Gaussian viewer through the checkpoint or formcheck file prepared.
