Thanks to Philip Bourne, the Protein Data Bank, and the San Diego Supercomputer Center for encouragement, to Helge Weissig and Kenneth Yoshimoto for interfacing with the PDB website, and John Badger for much useful advice and discussion. Thanks to Joel Sussman and Jaime Prilusky for their encouragement and collaborations initiated at the Brookhaven PDB and continuing at the Weizmann Institute of Science.

Portions of the MSA3D javascript were generously contributed by Paul Stothard. PE's script recorder was authored by Tim Driscoll. Thanks to Gale Rhodes, Kurt Giles, Craig Martin, Judith Voet, Frieda Reichsman, Tim Driscoll, Nicholas Keep, and Kim Henrick for helpful suggestions.

Paul Pillot made crucial contributions to adapting PE to operate in Internet Explorer by identifying and solving some of the major problems and demonstating that PE could operate reliably within IE. Thanks also to Jean-Philippe Demers who earlier had provided convincing evidence that operation in IE should be possible. Both contributions were initially made as volunteers. Thanks also to the Chime Team at MDL for quickly adapting Chime 2.6SP3 to work effectively with Microsoft's sudden changes in IE 5.5SP2.

Chime would not have been possible without the power and speed achieved by Roger Sayle in RasMol, and his generosity in putting RasMol's source code into the public domain. Thanks to Tim Maffett of MDLI for keeping nearly all of RasMol's power in Chime, for making Chime such a powerful tool, for implementing many requests that I made, and for crucial guidance. Thanks to Bryan van Vliet, Franklin Adler, Jean Holt and the rest of the Chime team at MDLI for Chime 2, and for much helpful advice. Thanks to Jean Holt for implementing my request for "show pdbheader" in Chime 2.6.
