# Acknowledgments

I am grateful to my PhD supervisor Professor Tom L. Blundell in whose laboratory at Birkbeck College the program was initiated.

I would also like to thank Professor Martin Karplus who allowed some of the data in the CHARMM topology and library files to be used with MODELLER.

I am in debt to the MODELLER users for their constructive criticisms and suggestions.
