Citing UCSF Chimera

Publications include scientific papers, posters, films, videos, exhibits, and artwork.

A substantial portion of the funding for the development of Chimera comes from a National Center for Research Resources grant (P41 RR-01081) from the National Institutes of Health. Consequently, publications that result from work using Chimera (e.g., contain graphical images produced with Chimera) should acknowledge our laboratory. We ask that a statement similar to the following be used:

Molecular graphics images were produced using the UCSF Chimera package from the Computer Graphics Laboratory, University of California, San Francisco (supported by NIH P41 RR-01081).

Please cite Chimera using the following:

Pettersen, E.F., Goddard, T.D., Huang, C.C., Couch, G.S., Greenblatt, D.M., Meng, E.C., and Ferrin, T.E. "UCSF Chimera - A Visualization System for Exploratory Research and Analysis." J. Comput. Chem. 25:1605-1612 (2004).


The solvent-excluded molecular surfaces produced by Chimera are created with the help of the MSMS package from Prof. Michel Sanner. Therefore, the use of Chimera images depicting solvent-excluded molecular surfaces should reference the following journal article in addition to the Chimera reference listed above:

Sanner, M.F., Olson, A.J., and Spehner, J.C. "Reduced surface: an efficient way to compute molecular surfaces." Biopolymers 38(3):305-320 (1996).

Also, please send us a reference to your publication for our records. We would also appreciate receiving two reprints of the publication. Our address is:

Prof. Thomas Ferrin
Computer Graphics Laboratory
University of California
600 16th Street
San Francisco, CA 94143-2240

Please note that NIH carefully tracks publications that make use of NCRR Resource Centers such as the CGL and hence your cooperation is appreciated in properly citing the grant number and references listed above. Thank you.


Chimera is the result of the work of many individuals: Conrad Huang, Greg Couch, Eric Pettersen, Thomas Ferrin, Tom Goddard, Daniel Greenblatt, Elaine Meng, David Konerding, Heidi Houtkooper, Teri Klein, Willa Crowell, Norma Belfer, Robin Parsons, and many others.
