cbioportal-core

Many of the Java classes here are in use by the main cbioportal/cbioportal codebase, the metaImport.py Python scripts are all used for importing. We decided to move them all to a single repo so that we might deprecate them in the future once we have come up with a good plan for replacing them.

This repo contains:

  • many old Java classes for interacting with the database
  • The metaImport.py Python script used for importing

Inclusion in main codebase

The cbioportal-core code is currently included in the final Docker image during the Docker build process: https://github.com/cBioPortal/cbioportal/blob/master/docker/web-and-data/Dockerfile#L48

Running in docker

Build docker image with:

docker build -t cbioportal-core .

Example of how to load study_es_0 study

Import gene panels

docker run -it -v $(pwd)/tests/test_data/:/data/ -v $(pwd)/application.properties:/application.properties cbioportal-core \
perl importGenePanel.pl --data /data/study_es_0/data_gene_panel_testpanel1.txt
docker run -it -v $(pwd)/tests/test_data/:/data/ -v $(pwd)/application.properties:/application.properties cbioportal-core \
perl importGenePanel.pl --data /data/study_es_0/data_gene_panel_testpanel2.txt

Import gene sets and supplementary data

docker run -it -v $(pwd)/src/test/resources/:/data/ -v $(pwd)/application.properties:/application.properties cbioportal-core \
perl importGenesetData.pl --data /data/genesets/study_es_0_genesets.gmt --new-version msigdb_7.5.1 --supp /data/genesets/study_es_0_supp-genesets.txt

Import gene set hierarchy data

docker run -it -v $(pwd)/src/test/resources/:/data/ -v $(pwd)/application.properties:/application.properties cbioportal-core \
perl importGenesetHierarchy.pl --data /data/genesets/study_es_0_tree.yaml

Import study

docker run -it -v $(pwd)/tests/test_data/:/data/ -v $(pwd)/application.properties:/application.properties cbioportal-core \
python importer/metaImport.py -s /data/study_es_0 -p /data/api_json_system_tests -o

Incremental upload of data

To add or update specific patient, sample, or molecular data in an already loaded study, you can perform an incremental upload. This process is quicker than reloading the entire study.

To execute an incremental upload, use the -d (or --data_directory) option instead of -s (or --study_directory). Here is an example command:

docker run -it -v $(pwd)/data/:/data/ -v $(pwd)/application.properties:/application.properties cbioportal-core python importer/metaImport.py -d /data/study_es_0_inc -p /data/api_json -o

Note: While the directory should adhere to the standard cBioPortal file formats and study structure, incremental uploads are not supported for all data types though. For instance, uploading study metadata, resources, or GSVA data incrementally is currently unsupported.

This method ensures efficient updates without the need for complete study reuploads, saving time and computational resources.

How to run integration tests

This section guides you through the process of running integration tests by setting up a cBioPortal MySQL database environment using Docker. Please follow these steps carefully to ensure your testing environment is configured correctly.

Preparing the cbioportal test database

  1. Download the cBioPortal Database Schema: To begin, you need to download the database schema for the version of cBioPortal you are interested in testing. Locate the pom.xml file in your project directory and check the values of <db.version> and <cbioportal.version> to determine the correct version. Replace v6.0.3 in the command below with your desired cBioPortal version:
curl -o cgds.sql https://raw.githubusercontent.com/cBioPortal/cbioportal/v6.0.3/src/main/resources/db-scripts/cgds.sql
  1. Launch the MySQL Server Container: Use Docker to start a MySQL server pre-loaded with the cBioPortal schema. Execute the following command from the root of your project directory. It is recommended to open a separate terminal tab or window for this operation as it will occupy the console until stopped:
docker run -p 3306:3306 \
-v $(pwd)/src/test/resources/seed_mini.sql:/docker-entrypoint-initdb.d/seed.sql:ro \
-v $(pwd)/cgds.sql:/docker-entrypoint-initdb.d/cgds.sql:ro \
-e MYSQL_ROOT_PASSWORD=root \
-e MYSQL_USER=cbio_user \
-e MYSQL_PASSWORD=somepassword \
-e MYSQL_DATABASE=cgds_test \
mysql:5.7

Run integration tests

With the database up and running, you are now ready to execute the integration tests.

Use Maven to run the integration tests. Ensure you are in the root directory of your project and run the following command:

mvn integration-test

Development

Prerequisites

To contribute to cbioportal-core, ensure you have the following tools installed:

  • Python 3: Required for study validation and orchestration scripts. These scripts utilize the underlying loader jar.
  • Perl: Specify the version required based on script compatibility. Necessary for data loading scripts interfacing with lookup tables.
  • JDK 21: Essential for developing the data loader component.
  • Maven 3.8.3: Used to compile and test the loader jar. Review this issue before starting.

Setup

  1. Create a Python virtual environment (first-time setup):
python -m venv .venv
  1. Activate the virtual environment:
source .venv/bin/activate
  1. Install required Python dependencies (first-time setup or when dependencies have changed):
pip install -r requirements.txt

Building and Testing

After you are done with the setup, you can build and test the project.

  1. Execute tests through the provided script:
./test_scripts.sh
  1. Build the loader jar using Maven (includes testing):
mvn clean package

Note: The Maven configuration is set to place the jar in the project's root directory to ensure consistent paths in both development and production.

Configuring Application Properties

The loader requires specific properties set to establish a connection to the database. These properties should be defined in the application.properties file within your project.

Creating the Properties File

  1. Begin by creating your application.properties file. This can be done by copying from an example or template provided in the project:
cp application.properties.example application.properties
  1. Open application.properties in your preferred text editor and modify the properties to match your database configuration and other environment-specific settings.

Setting the PORTAL_HOME Environment Variable

The PORTAL_HOME environment variable should be set to the directory containing your application.properties file, typically the root of your project:

export PORTAL_HOME=$(pwd)

Ensure this command is run in the root directory of your project, where the application.properties file is located. This setup is crucial for the loader to correctly access the required properties.

maven.properties

TODO: Document role of maven.properties file.

Script Execution with Loader Jar

To run scripts that require the loader jar, ensure the jar file is in the project root. The script will search for core-*.jar in the root of the project:

python scripts/importer/metaImport.py -s tests/test_data/study_es_0 -p tests/test_data/api_json_unit_tests -o
