VICC normalization routine for diseases

Disease Normalization

Services and guidelines for normalizing disease terms

Developer instructions

Following are sections include instructions specifically for developers.

Installation

For a development install, we recommend using Pipenv. See the pipenv docs for direction on installing pipenv in your compute environment.

Once installed, from the project root dir, just run:

pipenv sync

Deploying DynamoDB Locally

We use Amazon DynamoDB for our database. To deploy locally, follow these instructions.

Init coding style tests

Code style is managed by flake8 and checked prior to commit.

We use pre-commit to run conformance tests.

This ensures:

• Check code style
• Check for added large files
• Detect AWS Credentials
• Detect Private Key

Before first commit run:

pre-commit install

Running unit tests

Running unit tests is as easy as pytest.

pipenv run pytest

Updating the disease normalization database

Before you use the CLI to update the database, run the following in a separate terminal to start DynamoDB on port 8000:

java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb

To change the port, simply add -port value.

Update source(s)

The sources we currently use are: OncoTree, OMIM, Disease Ontology, and Mondo.

The application will automatically retrieve input data for all sources but OMIM, for which a source file must be manually acquired and placed in the disease/data/omim folder within the library root. In order to access OMIM data, users must submit a request here. Once approved, the relevant OMIM file (mimTitles.txt) should be renamed according to the convention omim_YYYYMMDD.tsv, where YYYYMMDD indicates the date that the file was generated, and placed in the appropriate location.

To update one source, simply set --normalizer to the source you wish to update. Accepted source names are DO (for Disease Ontology), Mondo, OncoTree, and OMIM.

From the project root, run the following to update the Mondo source:

python3 -m disease.cli --normalizer="Mondo"

To update multiple sources, you can use the normalizer flag with the source names separated by spaces.

python3 -m disease.cli --normalizer="Mondo OMIM DO"

Update all sources

To update all sources, use the --update_all flag.

From the project root, run the following to update all sources:

python3 -m disease.cli --update_all

Create Merged Concept Groups

The normalize endpoint relies on merged concept groups.

To create merged concept groups, use the --update_merged flag with the --update_all flag.

python3 -m disease.cli --update_all --update_merged

Specifying the database URL endpoint

The default URL endpoint is http://localhost:8000.

There are two different ways to specify the database URL endpoint.

The first way is to set the --db_url flag to the URL endpoint.

python3 -m disease.cli --update_all --db_url="http://localhost:8001"

The second way is to set the DISEASE_NORM_DB_URL to the URL endpoint.

export DISEASE_NORM_DB_URL="http://localhost:8001"
python3 -m disease.cli --update_all

Starting the disease normalization service

From the project root, run the following:

uvicorn disease.main:app --reload
