Dear Shabnam Nadjafi,

The complete information is on the Chimera website, see “licensing” here:
<http://www.rbvi.ucsf.edu/chimera/docs/licensing.html>

In summary:

Chimera is free for noncommercial use, but you will need to agree to the license that is automatically shown when you download the program.

To get Chimera for commercial use, you should contact chimera@cgl.ucsf.edu about the cost and terms.

Regards,
Elaine
