BRC Analytics Data Catalog

Building the data source files

Using Python version 3.12.4 is recommended.

Create a Python virtual environment and install requirements:

python3 -m venv ./venv
source ./venv/bin/activate
pip install -r ./catalog/build/py/requirements.txt

Then run the script:

npm run build-files-from-ncbi

The environment can be deactivated by running deactivate, and re-activated by running source ./venv/bin/activate again.

Building the catalog data

To build catalog data for use by the app, run the script:

npm run build-brc-db

Adding new assemblies

The list of assemblies is defined in the YAML file catalog/source/assemblies.yml. Assemblies are labeled with comments specifying the species name (as defined by NCBI), and sorted alphabetically by species.

To add a new assembly, add a new list item to the assemblies entry in the YAML, labeled and sorted as appropriate, consisting of a dictionary with a single entry, accession, specifying the assembly's accession.

For instance, to add a new assembly for Anopheles gambiae with the accession XXX_000000000.0, add this line below the # Anopheles gambiae comment:

- accession: XXX_000000000.0

Overview of automated checks on catalog content

The run-checks GitHub workflow performs checks to ensure that the catalog data and schemas are well-formed; this is done by:

• Linting the schemas via linkml-lint.
• Converting the schemas to Python, to catch any errors that occur.
• Validating the catalog source files against their corresponding schemas.
