Workflow Type: Unrecognized workflow type


This tutorial aims to illustrate how to compute a fast-growth mutation free energy calculation, step by step, using the BioExcel Building Blocks library (biobb). The particular example used is the Staphylococcal nuclease protein (PDB code 1STN), a small, minimal protein, appropriate for a short tutorial.

Workflow engine is a jupyter notebook. Auxiliary libraries used are nb_conda_kernels, os, and plotly. Environment setup can be carried out using the environment.yml in the code repository. The tutorial uses docker for running pmx - a local setup can be used instead, see notes in the tutorial.



Workflow Input files needed:

  • stateA_traj: Equilibrium trajectory for the WT protein.

  • stateB_traj: Equilibrium trajectory for the Mutated protein.

  • stateA_tpr: WT protein topology (GROMACS tpr format).

  • stateB_tpr: Mutated protein topology (GROMACS tpr format).

Auxiliar force field libraries needed:

  • mutff45 (folder): pmx mutation force field libraries.


  • pmx.outputs: Final free energy estimation. Summary of information got applying the different methods.

  • pmx.plots.png: Final free energy plot of the Mutation free energy pipeline.
