ChimeraX vs. Chimera:
ChimeraX and Chimera are different programs, with different interfaces and capabilities that overlap significantly, but not completely. ChimeraX is under active development and includes most Chimera features (with more to come, see the missing features list). It also has several completely new tools and other major advantages, including better performance on large data and modern software frameworks that extend its life far into the future. By contrast, Chimera has reached end-of-life and is no longer being developed or supported. Further, some Chimera tools that rely on web services may stop working entirely because the infrastructure they depend on is obsolete. For lists of the tools and commands in each program, see the respective User Guides: [ChimeraX] [Chimera]
These non-refundable fees are assessed per site (except for the global licenses) and do not include a company's affiliates or subsidiaries. Each company site, affiliate, or subsidiary must acquire a separate license. The licenses last for 3 years from the date of issuance. Currently developed software:
Single- and six-user licenses are assigned to specific named individuals, rather than floating among a larger set of people. For a given user based at a given site, however, there are no restrictions on the number of downloads during the 3-year period of the license; the user could have installations on multiple computers and/or different versions of the program on the same computer (production release, different daily builds, etc.). It is possible to reassign the license to a different user if, for example, someone leaves the company, but we require notification (email@example.com) of changes in the assigned user (1-user) or primary user (6-user or unlimited users). For a 6-user license, the company is responsible for maintaining its own list of the assigned individuals and ensuring that the number does not exceed six, but we do not need notification unless the primary user is changed.

UCSF's Office of Technology Management and Advancement will countersign and return the fully executed version. Please allow 4-6 weeks for processing time. (Steps #3-5 below can be carried out in parallel during this time.)
Downloads are available for recent versions of the Windows and macOS operating systems and some Linux distributions; other versions may not be supported. Chimera and ChimeraX are graphics-intensive programs intended for local, interactive use. We do not provide support for using them on compute clusters or virtual machines, or for remote display or remote rendering (details...).
