FoldX 5.0: working with RNA, small molecules and a new graphical interface

Bioinformatics. 2019 Oct 15;35(20):4168-4169. doi: 10.1093/bioinformatics/btz184.


Summary: A new version of FoldX, whose main new features allows running classic FoldX commands on structures containing RNA molecules and includes a module that allows parametrization of ligands or small molecules (ParamX) that were not previously recognized in old versions, has been released. An extended FoldX graphical user interface has also being developed (available as a python plugin for the YASARA molecular viewer) allowing user-friendly parametrization of new custom user molecules encoded using JSON format.
