🧬 How to use DockQ Online

Molecular Docking & Interactions Proteins

Use DockQ online for protein-protein docking benchmark assessment against native complexes.

DockQ is a benchmarking metric for judging how close a predicted protein-protein complex is to a reference native structure. Instead of forcing users to interpret several CAPRI-style criteria independently, the DockQ paper combines interface contact recovery and RMSD-based geometry into a single continuous score that is easier to compare across models.

On Neurosnap, researchers upload a Native Structure and a Model Structure to evaluate docking runs, folding-based complex predictions, or interface redesign models against a known reference. The workflow is useful when the scientific question is model accuracy, not de novo pose generation.

How DockQ Works

DockQ integrates Fnat, LRMS, and iRMS into a 0-1 quality measure that maps naturally onto the familiar CAPRI categories from incorrect to high quality. That makes it a better reporting metric than a single raw RMSD value, because it captures both interface correctness and overall placement of the docking partner.

On Neurosnap, Use Alpha-Carbon changes the atom set used for RMSD measurement, which can be helpful when side-chain or backbone completeness differs between structures, and Allowed Mismatches provides limited tolerance for sequence discrepancies before the comparison fails. Researchers typically use the DockQ score together with the native-contact map to diagnose whether a model failed because the interface is misplaced, because only some contacts were recovered, or because global chain orientation is wrong.

What is Neurosnap?

Neurosnap is the leading platform for bioinformatics and computational science focused on expanding access to powerful modeling and simulation tools. Because many state-of-the-art machine learning systems remain complex to install, configure, and scale, Neurosnap offers a clean, browser-based workspace that removes the burden of infrastructure management, dependency conflicts, and command-line tooling.

Built for biologists, chemists, and cross-disciplinary scientists, the platform enables advanced computational workflows without requiring expertise in software engineering or cloud architecture. Researchers can launch analyses through an intuitive interface, connect programmatically through a comprehensive API, and rely on automated resource management to scale workloads efficiently. By taking care of the underlying compute and operational complexity, Neurosnap allows teams to devote their energy to scientific progress and faster iteration. Security and data protection remain foundational principles, with clear safeguards outlined in our Terms of Use and Privacy Policy to ensure your work stays protected.

Advancing Discovery with DockQ on Neurosnap

Using DockQ on Neurosnap could drastically accelerate protein-protein docking model benchmarking against a native reference using DockQ.

Reference-based evaluation: DockQ is for judging docking accuracy against a known complex, which is exactly the right task for benchmarking or method comparison.
Composite quality score: Combining Fnat, LRMS, and iRMS yields a more interpretable quality measure than any one metric on its own.
Comparison controls: Use Alpha-Carbon and Allowed Mismatches help keep the evaluation robust when structures differ slightly in completeness or residue content.
Failure-mode diagnosis: Score tables plus native-contact views make it easier to see whether errors come from interface recovery, partner placement, or both.
