PyMod 3 is an open source PyMOL plugin, designed to act as an interface between PyMOL and several bioinformatics tools (for example: BLAST+, HMMER, Clustal Omega, MUSCLE, PSIPRED and MODELLER). The current PyMod release, PyMod 3, is compatible with the most recent PyMOL versions (see the Requirements section below) and has been extended with new functionalities with respect to its predecessor (PyMod 2). Starting from the amino acid sequence of a target protein, users may take advantage of PyMod 3 to carry out the three steps of the homology modeling process (that is, template searching, target-template sequence alignment and model building) in order to build a 3D atomic model of a target protein (or protein complex). Additionally, PyMod 3 may also be used outside the homology modeling context, in order to extend PyMOL with numerous types of functionalities. Sequence similarity searches, multiple sequence/structure alignment building, evolutionary conservation analyses, domain parsing and loop modeling can be performed in the PyMod 3/PyMOL environment.
PyMod 3 has been tested and runs on Windows, macOS and Linux versions of PyMOL. It is compatible with incentive PyMOL builds distributed by Schrodinger (required PyMOL version >= 2.3.4) and open source builds (required PyMOL version >= 2.3.0).

Please refer to the PyMod 3 User's Guide to learn how to install PyMod 3 on your system. Long story short: PyMod 3 can be installed as any other PyMOL plugin. Download the PyMod 3 plugin file (a ZIP file named pymod3.zip, see the link above) and use the PyMOL plugin manager (Plugin -> Plugin Manager from the menu of its main window) to install it. The external tools of PyMod 3 can be obtained and configured through an easy-to-use installer dialog which can be launched by the plugin (Help -> Install PyMod Components from the main menu of the plugin). The way to configure MODELLER in PyMod may vary according to your PyMOL version (in the User's Guide we cover different scenarios).
A series of introductory tutorials and in-depth information about all the PyMod 3 functionalities can be found in its User's Guide.
