Provenance tracking

iMicrobe data and analysis provenance are employed through CyVerse. Provenance tracking of both primary data, derived files, and analyses are tracked in CyVerse by keeping all files in the analysis directory, along with data products and a log file to maintain information about the job and parameters that were run. CyVerse also maintains the the job history (including the App id) to allow researchers to track and reproduce experiments. Data provenance is imperative given that data are derived from diverse data stores (iMicrobe Data Commons and a User’s Data Store) that have varied levels of curation and versioning. The job log file maintains the links to diverse data stores to allow users to confirm inputs to Apps.
