Dear Chimera and ChimeraX users, We will be doing some system maintenance on Monday, December 7. During this downtime, which we expect to last one day, the Chimera and ChimeraX websites, downloads, e-mailing lists, and several web services accessed by the programs will not be available. Apologies for any inconviences this may cause, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco
