How to use Interaction Fingerprint Online

Use Interaction Fingerprint online to compare protein-ligand interaction profiles across compounds with ProLIF.

Interaction Fingerprint encodes non-covalent contacts between a docked ligand and nearby protein residues into a ProLIF interaction fingerprint, then compares compounds using pairwise Tanimoto similarity. Upload one pre-docked complex per compound together with the matching SMILES list.

How Interaction Fingerprint Works

For each uploaded complex, the worker detects whether implicit or explicit hydrogens are appropriate, identifies the ligand by residue name or automatic HET detection, and runs ProLIF with the full interaction set. Results include a per-compound summary, a long-format interaction table, and a similarity matrix suitable for clustering chemotypes by interaction profile rather than by structure alone.

Upload two docked PDB files from a virtual screen and provide the corresponding SMILES in the same order, then compare the similarity heatmap to group compounds with shared hydrogen-bond or pi-stacking patterns.

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.
