Large-scale DNA sequencing studies of patients' tumors have revealed that most driver mutations occur only in a few patients, which presents a challenge for precision medicine. CHASMplus is a machine learning method that accurately distinguishes between driver and passenger missense mutations, even for those found at low frequencies or are cancer type-specific. Unlike previous approaches that focus on identifying driver genes, CHASMplus identifies whether individual mutations are cancer drivers. CHASMplus can be used by both bioinformaticians and biolgists by using a graphical user interface or a command line tool.

Note

You can run CHASMplus without installing anything by submitting your data to the OpenCRAVAT webserver (details here). After creating a user account, you'll just need to check the box for CHASMplus and hit the annotate button (OpenCRAVAT webserver). Also, you can install locally a graphical user interface [see the :ref:`quickstart-ref`]
