Instructions

DiffDock: Molecular Docking with Diffusion Models

Overview

DiffDock is a diffusion-based deep learning tool for molecular docking that predicts 3D binding poses of small molecule ligands to protein targets. It represents the state-of-the-art in computational docking, crucial for structure-based drug discovery and chemical biology.

Core Capabilities:

Predict ligand binding poses with high accuracy using deep learning
Support protein structures (PDB files) or sequences (via ESMFold)
Process single complexes or batch virtual screening campaigns
Generate confidence scores to assess prediction reliability
Handle diverse ligand inputs (SMILES, SDF, MOL2)

Key Distinction: DiffDock predicts binding poses (3D structure) and confidence (prediction certainty), NOT binding affinity (ΔG, Kd). Always combine with scoring functions (GNINA, MM/GBSA) for affinity assessment.

When to Use This Skill

This skill should be used when:

"Dock this ligand to a protein" or "predict binding pose"
"Run molecular docking" or "perform protein-ligand docking"
"Virtual screening" or "screen compound library"
"Where does this molecule bind?" or "predict binding site"
Structure-based drug design or lead optimization tasks
Tasks involving PDB files + SMILES strings or ligand structures
Batch docking of multiple protein-ligand pairs

Installation and Environment Setup

Check Environment Status

Before proceeding with DiffDock tasks, verify the environment setup:

# Use the provided setup checker
python scripts/setup_check.py

This script validates Python version, PyTorch with CUDA, PyTorch Geometric, RDKit, ESM, and other dependencies.

Installation Options

Option 1: Conda (Recommended)

git clone https://github.com/gcorso/DiffDock.git
cd DiffDock
conda env create --file environment.yml
conda activate diffdock

Option 2: Docker

docker pull rbgcsail/diffdock
docker run -it --gpus all --entrypoint /bin/bash rbgcsail/diffdock
micromamba activate diffdock

Important Notes:

GPU strongly recommended (10-100x speedup vs CPU)
First run pre-computes SO(2)/SO(3) lookup tables (~2-5 minutes)
Model checkpoints (~500MB) download automatically if not present

Core Workflows

Workflow 1: Single Protein-Ligand Docking

Use Case: Dock one ligand to one protein target

Input Requirements:

Protein: PDB file OR amino acid sequence
Ligand: SMILES string OR structure file (SDF/MOL2)

Command:

python -m inference \
  --config default_inference_args.yaml \
  --protein_path protein.pdb \
  --ligand "CC(=O)Oc1ccccc1C(=O)O" \
  --out_dir results/single_docking/

Alternative (protein sequence):

python -m inference \
  --config default_inference_args.yaml \
  --protein_sequence "MSKGEELFTGVVPILVELDGDVNGHKF..." \
  --ligand ligand.sdf \
  --out_dir results/sequence_docking/

Output Structure:

results/single_docking/
├── rank_1.sdf          # Top-ranked pose
├── rank_2.sdf          # Second-ranked pose
├── ...
├── rank_10.sdf         # 10th pose (default: 10 samples)
└── confidence_scores.txt

Workflow 2: Batch Processing Multiple Complexes

Use Case: Dock multiple ligands to proteins, virtual screening campaigns

Step 1: Prepare Batch CSV

Use the provided script to create or validate batch input:

# Create template
python scripts/prepare_batch_csv.py --create --output batch_input.csv

# Validate existing CSV
python scripts/prepare_batch_csv.py my_input.csv --validate

CSV Format:

complex_name,protein_path,ligand_description,protein_sequence
complex1,protein1.pdb,CC(=O)Oc1ccccc1C(=O)O,
complex2,,COc1ccc(C#N)cc1,MSKGEELFT...
complex3,protein3.pdb,ligand3.sdf,

Required Columns:

complex_name: Unique identifier
protein_path: PDB file path (leave empty if using sequence)
ligand_description: SMILES string or ligand file path
protein_sequence: Amino acid sequence (leave empty if using PDB)

Step 2: Run Batch Docking

python -m inference \
  --config default_inference_args.yaml \
  --protein_ligand_csv batch_input.csv \
  --out_dir results/batch/ \
  --batch_size 10

For Large Virtual Screening (>100 compounds):

Pre-compute protein embeddings for faster processing:

# Pre-compute embeddings
python datasets/esm_embedding_preparation.py \
  --protein_ligand_csv screening_input.csv \
  --out_file protein_embeddings.pt

# Run with pre-computed embeddings
python -m inference \
  --config default_inference_args.yaml \
  --protein_ligand_csv screening_input.csv \
  --esm_embeddings_path protein_embeddings.pt \
  --out_dir results/screening/

Workflow 3: Analyzing Results

After docking completes, analyze confidence scores and rank predictions:

# Analyze all results
python scripts/analyze_results.py results/batch/

# Show top 5 per complex
python scripts/analyze_results.py results/batch/ --top 5

# Filter by confidence threshold
python scripts/analyze_results.py results/batch/ --threshold 0.0

# Export to CSV
python scripts/analyze_results.py results/batch/ --export summary.csv

# Show top 20 predictions across all complexes
python scripts/analyze_results.py results/batch/ --best 20

The analysis script:

Parses confidence scores from all predictions
Classifies as High (>0), Moderate (-1.5 to 0), or Low (<-1.5)
Ranks predictions within and across complexes
Generates statistical summaries
Exports results to CSV for downstream analysis

Confidence Score Interpretation

Understanding Scores:

Score Range	Confidence Level	Interpretation
> 0	High	Strong prediction, likely accurate
-1.5 to 0	Moderate	Reasonable prediction, validate carefully
< -1.5	Low	Uncertain prediction, requires validation

Critical Notes:

Confidence ≠ Affinity: High confidence means model certainty about structure, NOT strong binding
Context Matters: Adjust expectations for:
- Large ligands (>500 Da): Lower confidence expected
- Multiple protein chains: May decrease confidence
- Novel protein families: May underperform
Multiple Samples: Review top 3-5 predictions, look for consensus

For detailed guidance: Read references/confidence_and_limitations.md using the Read tool

Parameter Customization

Using Custom Configuration

Create custom configuration for specific use cases:

# Copy template
cp assets/custom_inference_config.yaml my_config.yaml

# Edit parameters (see template for presets)
# Then run with custom config
python -m inference \
  --config my_config.yaml \
  --protein_ligand_csv input.csv \
  --out_dir results/

Key Parameters to Adjust

Sampling Density:

samples_per_complex: 10 → Increase to 20-40 for difficult cases
More samples = better coverage but longer runtime

Inference Steps:

inference_steps: 20 → Increase to 25-30 for higher accuracy
More steps = potentially better quality but slower

Temperature Parameters (control diversity):

temp_sampling_tor: 7.04 → Increase for flexible ligands (8-10)
temp_sampling_tor: 7.04 → Decrease for rigid ligands (5-6)
Higher temperature = more diverse poses

Presets Available in Template:

High Accuracy: More samples + steps, lower temperature
Fast Screening: Fewer samples, faster
Flexible Ligands: Increased torsion temperature
Rigid Ligands: Decreased torsion temperature

For complete parameter reference: Read references/parameters_reference.md using the Read tool

Advanced Techniques

Ensemble Docking (Protein Flexibility)

For proteins with known flexibility, dock to multiple conformations:

# Create ensemble CSV
import pandas as pd

conformations = ["conf1.pdb", "conf2.pdb", "conf3.pdb"]
ligand = "CC(=O)Oc1ccccc1C(=O)O"

data = {
    "complex_name": [f"ensemble_{i}" for i in range(len(conformations))],
    "protein_path": conformations,
    "ligand_description": [ligand] * len(conformations),
    "protein_sequence": [""] * len(conformations)
}

pd.DataFrame(data).to_csv("ensemble_input.csv", index=False)

Run docking with increased sampling:

python -m inference \
  --config default_inference_args.yaml \
  --protein_ligand_csv ensemble_input.csv \
  --samples_per_complex 20 \
  --out_dir results/ensemble/

Integration with Scoring Functions

DiffDock generates poses; combine with other tools for affinity:

GNINA (Fast neural network scoring):

for pose in results/*.sdf; do
    gnina -r protein.pdb -l "$pose" --score_only
done

MM/GBSA (More accurate, slower): Use AmberTools MMPBSA.py or gmx_MMPBSA after energy minimization

Free Energy Calculations (Most accurate): Use OpenMM + OpenFE or GROMACS for FEP/TI calculations

Recommended Workflow:

DiffDock → Generate poses with confidence scores
Visual inspection → Check structural plausibility
GNINA or MM/GBSA → Rescore and rank by affinity
Experimental validation → Biochemical assays

Limitations and Scope

DiffDock IS Designed For:

Small molecule ligands (typically 100-1000 Da)
Drug-like organic compounds
Small peptides (<20 residues)
Single or multi-chain proteins

DiffDock IS NOT Designed For:

Large biomolecules (protein-protein docking) → Use DiffDock-PP or AlphaFold-Multimer
Large peptides (>20 residues) → Use alternative methods
Covalent docking → Use specialized covalent docking tools
Binding affinity prediction → Combine with scoring functions
Membrane proteins → Not specifically trained, use with caution

For complete limitations: Read references/confidence_and_limitations.md using the Read tool

Troubleshooting

Common Issues

Issue: Low confidence scores across all predictions

Cause: Large/unusual ligands, unclear binding site, protein flexibility
Solution: Increase samples_per_complex (20-40), try ensemble docking, validate protein structure

Issue: Out of memory errors

Cause: GPU memory insufficient for batch size
Solution: Reduce --batch_size 2 or process fewer complexes at once

Issue: Slow performance

Cause: Running on CPU instead of GPU
Solution: Verify CUDA with python -c "import torch; print(torch.cuda.is_available())", use GPU

Issue: Unrealistic binding poses

Cause: Poor protein preparation, ligand too large, wrong binding site
Solution: Check protein for missing residues, remove far waters, consider specifying binding site

Issue: "Module not found" errors

Cause: Missing dependencies or wrong environment
Solution: Run python scripts/setup_check.py to diagnose

Performance Optimization

For Best Results:

Use GPU (essential for practical use)
Pre-compute ESM embeddings for repeated protein use
Batch process multiple complexes together
Start with default parameters, then tune if needed
Validate protein structures (resolve missing residues)
Use canonical SMILES for ligands
