Database Versions | One Codex Docs

The One Codex Database is designed to be completely reproducible and rigorously versioned. This includes all parts of the analysis, including the contents of the genome database itself, our classification and filtering algorithms, the execution environment, and the format of the output files. Consequently, every analysis performed on One Codex can be uniquely identified by its Job Version ID, which is a 16 character alphanumeric unique identifier. You can find the Job Version ID for any analysis at the bottom of the analysis results page.

An example Job Version ID from the bottom of an analysis page.

This page lists all of the historical Job Version IDs for the One Codex Database, so you can reference what changes were made in each new release. You can always run the latest version of the One Codex Database (while still having access to previous analyses) from the Jobs page on One Codex. If you'd like to run an older version of the analysis, please contact us.

Job Version ID	Release Date	Notes
`77addd840ee7481c`	November 4, 2024	2024 database release, including the following notable changes: the addition of new hosts. We've added the chicken and rat genomes to the database, for users working with microbiome samples from these hosts. We've also added the new telomere-to-telomere (T2T CHM13v2.0) human genome assembly (in addition to the hg38 assembly that was present in previous databases). Updated taxonomy to capture newly-classified taxa. Improved flu specificity, with many more flu genomes addition of more metagenome-assembled genomes (MAGs) from diverse studies
`89e364d51abe46e0`	June 30, 2023	2023 database release, including increased viral genomes, with a particular focus on pathogens.
`53171acf54844bc4`	September 15, 2022	2022 database release, including more mouse-associated microbes and MAGs.
`9fadceb4d8134547`	July 25, 2022	Revision to 2020 database to remove erroneous genome from read-level results
`bb24767f1561436f`	June 03, 2022	Revision to 2020 database to remove erroneous genome from abundance-level results
`7caed8f5319e42e1`	August 08, 2021	Revision to 2020 database to include additional viruses
`7b66648cf0fd4c47`	August 27, 2020	2020 database release, including more viruses, and mouse host genome.

`a76e9f6d3b23445d`	June 24, 2019	Classifier update to improve estimation of microbial abundances for a small subset of high-host samples. Database contents are identical to `d8c5e103dc7d4d96`.
`d8c5e103dc7d4d96`	February 01, 2019	2019 database release.
`1ece475718ab4310`	August 23, 2018	Backwards-compatible classifier update to support FASTQ files with missing records. Identical results to `a83ff978d40c4314` for all valid FASTQ files.
`a83ff978d40c4314`	March 18, 2018	Updates to classifier, with a focus on improved FASTQ handling for a variety of edge cases. Database contents are the same as `14ad3cf0a61849e2`.
`cd273763c4f44fbe`	March 01, 2018	Minor update to classifier to: (1) reduce size of internal results format; and (2) support mixed casing nucleotide sequences. Database contents are the same as `14ad3cf0a61849e2`
`14ad3cf0a61849e2`	February 10, 2018	2018 database release.
