biothings_client is an easy-to-use Python wrapper to access any Biothings.api -based backend service. Currently, the following clients are available:
- gene - The client for MyGene.Info, which provides access to gene objects.
- variant - The client MyVariant.Info, which provides access to genetic variant objects.
- chem - The client for MyChem.Info, which provides access to chemical/drug objects.
- disease - The client for MyDisease.Info, which provides access to disease objects.
- geneset - The client for MyGeneset.Info, which provides access to geneset/pathway objects.
- taxon - The client for t.biothings.io, which provides access to taxon objects.
python >=2.7 (including all python3 versions)
(It may still work under python 2.6, but it's not supported any more.)
requests (install using "pip install requests")
- pandas (install using "pip install pandas") is required for returning a list of variant objects as DataFrame.
- requests_cache (install using "pip install requests_cache") is required for local caching of API requests.
- Option 1
pip install biothings_client- Option 2
download/extract the source code and run:
python setup.py install- Option 3
install the latest code directly from the repository:
pip install -e git+https://github.com/biothings/biothings_client.py#egg=biothings_client
