Molecular Dynamics (OpenMM + MDAnalysis)
Set up, run, and analyze protein/ligand MD simulations end-to-end with OpenMM and MDAnalysis.

What it does
- Prepares systems from PDB files: hydrogen addition, 10 Å solvent padding, 150 mM ionic strength, PME electrostatics.
- Provides the standard pipeline as ready-to-run functions: energy minimization → NVT equilibration → NPT production, with GPU (CUDA/OpenCL) fallback and checkpointing.
- Analyzes trajectories with MDAnalysis: RMSD time series, per-residue RMSF, protein–ligand contact tracking, and matplotlib plots.
- Includes a force-field selection table by system type, PDBFixer preprocessing, and OpenFF/GAFF2 ligand parameterization.
Who it's for
- Structural biologists, computational chemists, and bioinformatics grad students.
- Drug discovery teams validating ligand binding modes and stability.
- Anyone quantifying how a mutation changes protein flexibility.
Examples
- "Clean this PDB with PDBFixer and run a 1 ns NPT simulation using amber14 + TIP3P-FB."
- "Compute backbone RMSD and per-residue RMSF from npt_traj.dcd and plot them."
- "List residues within 4.5 Å of the ligand (resname LIG) for each frame of the trajectory."

Paste this into Claude to use the skill without installing anything.
Read the instructions in this file and follow them to help me: https://raw.githubusercontent.com/K-Dense-AI/scientific-agent-skills/HEAD/skills/molecular-dynamics/SKILL.md What I want: (describe your task here)
If Claude can't open the link, open it yourself and paste the contents instead.
↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.
Install in the Claude app (no terminal)
- Download the ZIP with the button below.
- In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
- Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
Install in Claude Code
Let Claude do it — paste this into Claude Code
Install the skill I found on Claude Skill Mart. Copy the skills/molecular-dynamics folder from the GitHub repo K-Dense-AI/scientific-agent-skills into my ~/.claude/skills/molecular-dynamics/. When it's done, tell me in one line what this skill can do.
Install with a command instead
git clone https://github.com/K-Dense-AI/scientific-agent-skills.git && mkdir -p ~/.claude/skills && cp -r scientific-agent-skills/skills/molecular-dynamics ~/.claude/skills/⚠ This is a third-party skill. Check the source repository before installing.
- Clone the repository:
git clone https://github.com/K-Dense-AI/scientific-agent-skills.git - Create the skills directory:
mkdir -p ~/.claude/skills - Copy this skill only:
cp -r scientific-agent-skills/skills/molecular-dynamics ~/.claude/skills/ - Install the scientific stack:
conda install -c conda-forge openmm mdanalysis nglview pdbfixer - For GPU runs, verify your CUDA driver and check platforms with
python -m openmm.testInstallation. - Restart Claude Code, then ask something like "prepare an MD simulation for this PDB" to trigger the skill.
