Help needed for gmx_MMPBSA! To the content creators out there...

gmx_MMPBSA is a new tool based on AMBER's MMPBSA.py aiming to perform end-state free energy calculations with GROMACS files. It works with all GROMACS versions along with AmberTools >=20 and brings improvements in compatibility, versatility, analyses, and parallelization compared to existing programs (see here for a detailed comparison)

What can be done with gmx_MMPBSA?

Multiple calculations can be performed with gmx_MMPBSA such as:

There is always more...

You can check gmx_MMPBSA in a nutshell page for a more detailed overview of the types of calculations supported in gmx_MMPBSA. Also check our example page to see a detailed list of all the examples available

In the current version, gmx_MMPBSA supports a number of different systems including but not limited to:

Support for Amber, OPLS and CHARMM force fields

In the current version, gmx_MMPBSA supports Amber, OPLS and CHARMM force fields. Any system built for GROMACS with either pdb2gmx or CHARMM-GUI is supported in gmx_MMPBSA. Likewise, any system built for NAMD and potentially any other software that uses *.psf - *.dcd files can be processed in gmx_MMPBSA 😀. Check our example page to see a detailed list of all the examples available.

The following video shows how a typical binding free energy calculation with GB model and Interaction entropy method is performed in gmx_MMPBSA.

gmx_MMPBSA a quick overview

gmx_MMPBSA is a python module that contains 3 applications:

  • gmx_MMPBSA is the fundamental application and carries out the calculations mentioned above
  • gmx_MMPBSA_ana provides an intuitive way to analyze the data from gmx_MMPBSA calculations and save high-quality pictures
  • gmx_MMPBSA_test is a tool designed to test if the installation was successful by running one or more available examples in gmx_MMPBSA.

Easy to run

gmx_MMPBSA can run in parallel and requires just few things in order to perform any kind of calculation. That is:

  • an input parameters file (*.in, contains all the specifications regarding the type of calculation that is going to be performed)
  • a MD Structure+mass(db) file (*.tpr, *.pdb)
  • an index file (*.ndx)
  • receptor and ligand groups (group numbers in the index file)
  • a trajectory file (*.xtc, *.pdb, *.trr)
  • In certain occasions, defining a topology file (*.top) may be required.

Once the calculation is done, you can analyze the results in gmx_MMPBSA_ana

You can check How gmx_MMPBSA works page to get more details. Also check our example page to see how gmx_MMPBSA works with real examples

Collaboration

gmx_MMPBSA is rapidly becoming one of the main programs to perform end-point free energy calculations out there (~29k downloads so far). We are currently focused on optimizing the program, supporting new types of calculations, force fields, etc. However, the video tutorials are not that great.

That being said, and here is where we need help, we will appreciate any collaboration in making video tutorials for the documentation. The video tutorial will be included as a link to YouTube in gmx_MMPBSA documentation with full acknowledgment of the person who created the video tutorial. It will be also acknowledged as a contributor of gmx_MMPBSA... 😃

Feel free to contact us through our google group (https://groups.google.com/g/gmx_mmpbsa) for more details...
