PyMOL is a molecular visualization system

PyMOL is a molecular visualization system created by Warren Lyford DeLano and commercialized initially by DeLano Scientific LLC, which was a private software company dedicated to creating useful tools that become universally accessible to scientific and educational communities. It is currently commercialized by Schrödinger, Inc. PyMOL can produce high-quality 3D images of small molecules and biological macromolecules, such as proteins.

PyMOL is one of a few free visualization tools available for use in structural biology. The Py portion of the software's name refers to the fact that it extends, and is extensible by the Python programming language.

PyMOL uses OpenGL Extension Wrangler Library (GLEW) and Freeglut, and can solve Poisson–Boltzmann equations using the Adaptive Poisson Boltzmann Solver.
