About Workshop
Participants will perform system preparation, equilibration, production MD, trajectory analysis and interaction profiling.
The workshop also covers MM/PBSA binding-energy analysis, residue-level contributions and dynamic interaction fingerprints.
By integrating structural stability and binding energetics, participants will develop an evidence-based approach for ligand prioritisation and computational drug discovery.
Aim
To equip participants with practical skills in protein–ligand molecular dynamics, trajectory analysis, interaction assessment and MM/PBSA interpretation for computational drug discovery and structural biology research.

- Process molecular dynamics trajectories correctly.
- Analyse RMSD, RMSF, radius of gyration and SASA.
- Evaluate hydrogen bonds, residue contacts and ligand movement.
- Perform and interpret MM/PBSA calculations.
- Prepare publication-quality plots, tables and summaries.
Structure
Day 1: Protein–Ligand System Preparation & Energy Minimisation
Core Objective: Prepare a docked protein–ligand complex and convert it into a simulation-ready molecular system for GROMACS-based MD simulation.- Inspect and prepare the protein–ligand complex, generate protein topology, and create ligand parameters compatible with the selected force field.
- Define the simulation box, solvate the complex with explicit water, add counter-ions, and neutralise the molecular system.
- Perform energy minimisation and evaluate potential energy and structural quality before proceeding to equilibration.
Hands-on Lab: Prepare a protein–ligand complex in Google Colab, generate the required topology and ligand parameters, solvate and neutralise the system, and perform energy minimisation to obtain a simulation-ready structure.
Tools Covered: GROMACS, Google Colab, ACPYPE/AmberTools, PyMOL/Py3Dmol
Output: Simulation-ready, solvated and energy-minimised protein–ligand complex.
Day 2: Equilibration & Production Molecular Dynamics Simulation
Core Objective: Equilibrate the prepared protein–ligand system, initiate production MD simulation, and verify that the system is suitable for downstream trajectory analysis.- Perform NVT equilibration to stabilise system temperature and NPT equilibration to stabilise pressure and density.
- Evaluate temperature, pressure, density and potential-energy profiles to assess whether the molecular system has achieved suitable equilibration.
- Configure production MD parameters, initiate the simulation, and prepare the resulting trajectory for subsequent structural analysis.
Hands-on Lab: Run NVT and NPT equilibration of the prepared protein–ligand system, generate temperature, pressure and density QC plots, and initiate a production MD simulation in GROMACS. A validated longer trajectory will be provided for complete downstream analysis.
Tools Covered: GROMACS, Google Colab, Python, Matplotlib
Output: Equilibrated system, simulation-QC plots, production-MD setup and analysis-ready trajectory.
Day 3: MD Trajectory, Structural Stability & Protein–Ligand Interaction Analysis
Core Objective: Analyse the MD trajectory to determine protein stability, ligand retention, conformational behaviour and persistence of key protein–ligand interactions.- Process and align the trajectory, then calculate protein RMSD, ligand RMSD, RMSF and radius of gyration to evaluate structural and conformational stability.
- Analyse hydrogen-bond occupancy and protein–ligand contacts to determine whether important binding-site interactions persist during the simulation.
- Generate dynamic interaction fingerprints and identify persistent, transient, lost and newly formed interactions between the ligand and binding-site residues.
Hands-on Lab: Analyse a protein–ligand MD trajectory to generate RMSD, RMSF and radius-of-gyration plots, quantify hydrogen-bond persistence, and build a dynamic protein–ligand interaction fingerprint for binding-site interpretation.
Tools Covered: GROMACS, MDAnalysis, ProLIF, Python, Matplotlib, Google Colab
Output: Structural-stability plots, hydrogen-bond profile, residue-contact analysis and dynamic protein–ligand interaction fingerprint.
Day 4: MM/PBSA Binding-Energy Analysis & Ligand Prioritisation
Core Objective: Estimate protein–ligand binding energetics, identify important energetic residues, and integrate molecular dynamics evidence for research-oriented ligand evaluation.- Select representative equilibrated trajectory frames and calculate MM/PBSA energetic components including van der Waals, electrostatic, polar and non-polar solvation contributions.
- Perform per-residue energy decomposition to identify favourable and unfavourable residues contributing to protein–ligand binding.
- Integrate structural stability, interaction persistence and MM/PBSA results to compare candidate ligands and develop a scientifically supported interpretation.
Hands-on Lab: Perform MM/PBSA analysis on selected MD trajectory frames, generate binding-energy and residue-contribution plots, identify key binding residues, and combine structural and energetic evidence to prioritise the candidate ligand.
Tools Covered: GROMACS, gmx_MMPBSA, AmberTools, Python, Pandas, Matplotlib, Google Colab
Output: MM/PBSA results, residue-energy contributions, key binding residues and an evidence-based ligand-prioritisation summary.Important Dates
