Terms of Usage for the PyMOL User's Manual

This manual is NOT free. It is a PyMOL Incentive Product created to help you use the program while also generating recurring sponsorship for the project. This manual is made available for evaluation via the "honor" system: You may evaluate this manual for a continuous period of up to one year without obligation. If you wish to continue using this document beyond the end of the evaluation period, then you must become a sponsor of the project by purchasing a PyMOL license and a subscription to maintenance and support from DeLano Scientific LLC (

Of course, if you are willing to sponsor the project today, then please don't wait a full year to start. The sooner your sponsorship comes in, the sooner we can apply it to improve the software and documentation!

Existing PyMOL subscribers may use this manual for no additional cost. However, subscribers who do not renew their subscription upon expiration must discountinue use of this and all other PyMOL Incentive Products. Though we have no direct means of enforcing this, we ask, in recognition of our declared scientific mission, that you honor the trust placed in you.

PyMOL users who are unable to sponsor the project by purchasing a PyMOL license and maintenance subscription are welcome to use Open-Source versions of PyMOL and any free documentation that can be found on the internet.
