datanator is a software tool for finding experimental data for building and calibrating dynamical models of cellular biochemistry such as metabolite, RNA, and protein abundances; protein complex compositions; transcription factor binding motifs; and kinetic parameters.
datanator is particularly useful for building large models, such as whole-cell models, that require large amounts of data to constrain large numbers of parameters.
datanator was motivated by the need for large amounts of data to constrain whole-cell models and the fact that this data is hard to utilize because it is scattered across numerous siloed repositories.
datanator currently supports the following data types and data sources:
- Metabolite concentrations: ECMDB and YMBD
- RNA abundance: ArrayExpress
- Protein abundance: PaxDb
- Protein complex composition: CORUM
- Transcription factor binding motifs: JASPAR
- Reaction kinetics: SABIO-RK
- Taxonomy: NCBI Taxonomy
datanator (1) downloads these repositories; (2) normalizes their data to a common ontology and units; (3) stores their data to a local SQLite database; and (4) provides a Python API for (a) finding relevant data to model a specific organism and environmental condition from similar species, reactions, genotypes (taxon, variant), and environments (temperature, pH, media), and (b) reducing multiple relevant observations to a single consensus recommended parameter value, and (c) exporting these consensus recommendations and their provenance to an Excel workbook. To make
datanator easier to use, we plan to develop user-friendly command line and web-based interfaces for finding data for SBML-encoded models.
datanator is under active development and is not yet ready for end users. Please check back soon for updates.
