Steinbeck Lab: open software for chemistry and natural products, Natural Products Cheminformatics, Friedrich Schiller University Jena

cheminf.uni-jena.de naturalproducts.net All repositories

This organisation hosts the research software of the Steinbeck Lab at Friedrich Schiller University Jena. Open science, open source, open data.

COCONUT, the COlleCtion of Open Natural prodUcTs: deposit, curate and reuse natural product data. DECIMER.ai: extract chemical structures from PDFs and images, and turn them into SMILES. ChemAudit: validate, standardize and score chemical structures before they feed a model or a database. Cheminformatics Microservice: CDK, RDKit and Open Babel, unified behind one REST API and web app. MORTAR, the MOlecule fRagmenTAtion fRamework: in silico fragmentation on the desktop. Orthonym: deterministic structure-to-IUPAC names, each checked by an OPSIN round trip. SURGE: a fast open-source chemical graph generator for every isomer of a formula. Sherlock: computer-assisted structure elucidation, from NMR spectra to structures.

More from the lab: STOUT (SMILES to IUPAC names), CIDER (chemical dataset comparison), and everything else.

Built on CDK, RDKit, Open Babel and OPSIN, in Python, Java, C, PHP and TypeScript, shipped with Docker.

Brewed in Jena since 1997

    DECIMER Image Transformer is a deep-learning-based tool designed for automated recognition of chemical structure images. Leveraging transformer architectures, the model converts chemical images into SMILES strings, enabling the digitization of chemical data from scanned documents, literature, and patents.
