SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automates large-scale protein-ligand virtual screening to produce ranked ligand poses and summary metrics, eliminating manual orchestration of docking, scoring corrections, and output collection for downstream analysis and verification.

Core Features & Use Cases

  • Batch Virtual Screening: Run KarmaDock on ligand SMILES libraries against a target protein PDB with optional crystal ligand MOL2 pocket localization.
  • Robust Scoring & Correction: Produces karma_score plus force-field and alignment-corrected scores (karma_score_ff, karma_score_aligned) for reliable ranking.
  • Pose Export & Reproducibility: Exports ranked pose SDF files and enforces mandatory download policies to ensure local verification and reproducibility.
  • Operational Modes: Supports dry-run validation, configurable score_threshold, batch_size, and random_seed for reproducible campaigns.
  • Use Case: Pre-screen a 100k-compound library to obtain top-ranked poses for rescoring, MD validation, or interaction fingerprint analysis.

Quick Start

Run KarmaDock to screen a ligand library against a protein structure, generate ranked pose SDFs, and download the outputs for downstream analysis.

FAQPage Schema
How do I run high-throughput virtual screening on a large ligand SMILES library?

KarmaDock automates protein-ligand virtual screening by running batch docking on ligand SMILES libraries against a target protein PDB, generating ranked pose SDF files and summary metrics for downstream analysis without manual orchestration.

What scoring metrics are produced during protein-ligand molecular screening?

Protein-ligand molecular screening with KarmaDock produces three scoring metrics: karma_score, karma_score_ff (force-field corrected), and karma_score_aligned (alignment-corrected). These robust scores ensure reliable ligand ranking and rescoring for high-throughput campaigns.

Do I need a crystal ligand MOL2 file for KarmaDock pocket localization?

A crystal ligand MOL2 file is optional for pocket localization in KarmaDock virtual screening. You must provide a target protein PDB, but the crystal ligand MOL2 is only supplied when you need precise pocket definition for batch ligand docking workflows.

Can I configure batch size and score thresholds for ligand ranking?

KarmaDock supports configurable score_threshold, batch_size, and random_seed parameters for reproducible ligand ranking. These operational modes allow precise control over high-throughput virtual screening campaigns and ensure consistent results across batch docking runs.

How do I retrieve ranked SDF pose files after virtual screening?

Retrieving ranked SDF pose files requires completing the mandatory output download step after KarmaDock finishes virtual screening. This enforced policy ensures you locally download exported pose files for verification, reproducibility, and downstream analysis.

What is the best way to validate a 100k-compound library before rescoring?

Validating a large compound library before rescoring uses KarmaDock's dry-run validation mode. You can pre-screen a 100k-compound library with configurable batch sizes to obtain top-ranked poses efficiently for subsequent MD validation or interaction fingerprint analysis.
