Good afternoon, I am writing to you in the kindest way to request a free use license for the chimera X program.  Because I am a student at the National Autonomous University of Mexico (UNAM), within the Faculty of Sciences, and it would be a great opportunity to use your tool in different molecular biology analyses.
If you need a proof of my identity as a student, you can ask me for it without any problem.

I look forward to hearing from you. Best regards.
