FoldX 5.0 has been released, read more.

The FoldX Suite features a brand new human writable-readable boost based command line interface. To work with foldx follow these advises:

  • Add the binary location to PATH environment variable.
  • The file rotabase.txt or a soft link still need to be in the working directory for version 4, but it is automatically created for version5 (if you are not sure which version of the rotabase.txt you are using with version 5, just delete it and it will be created again).
  • Please consider repairing the pdb as a must for any further command.

Command Line

FoldX --command=YourCommand --pdb=YourPDB ...[--more-parameters]

Config File

The config.cfg file contains everything you need to run FoldX, including general and specific commands, as well as I/O options. Different parameters are written into different lines (one parameter per line). Examples of configuration files can be found in the corresponding pages of all commands. Foldx3b6 and previous runfiles wont work anymore. If some parameters are not set, defaults options will be used (although some commands may require command specific parameters). FoldX only recognizes certain residues, the rest will be discarded before any calculation is taken, you can find a list of allowed residues here.

FoldX -f config.cfg

Interactive Help

Interactive help about commands and parameters can be obtained directly at the command line by using the following syntax:

FoldX --help

More specific help about the commands can be obtained by specifying the command name, e.g.:

FoldX --help --command=BuildModel

Fragment Library Installation
