Quick Start

Get up and running with synth-pdb in 5 minutes.

Installation

pip install synth-pdb

git clone https://github.com/elkins/synth-pdb.git
cd synth-pdb
pip install .

Your First Structure

Generate a simple 10-residue alpha helix:

synth-pdb --length 10 --conformation alpha --output my_first_helix.pdb

This creates a PDB file with: - ✅ Full atomic representation (backbone + side-chains + hydrogens) - ✅ Realistic B-factors and occupancy values - ✅ Proper bond geometry and angles

Visualize It

View your structure interactively in the browser:

synth-pdb --length 10 --conformation alpha --visualize

Add Physics

Generate a more realistic structure with energy minimization:

synth-pdb --length 20 --conformation alpha --minimize --output minimized.pdb

This uses OpenMM to: - Regularize bond lengths and angles - Resolve steric clashes - Apply implicit solvent effects
