PyMod 3 is a PyMOL plugin, designed to act as simple and intuitive interface between PyMOL and several bioinformatics tools (i.e., PSI-BLAST, Clustal Omega, MUSCLE, CAMPO, PSIPRED, and MODELLER). The current PyMod release, PyMod 3, has been extended with a rich set of functionalities that substantially improve it over its predecessor (PyMod 2.0), particularly in its ability to build homology models through the popular MODELLER package.

PyMod 3 runs on Windows, macOS and Linux. It is compatible with PyMOL versions >= 2.3 and has been developed and tested on both incentive PyMOL builds (distributed by Schrodinger) and open source builds.
