hubmap-api-py-client

Python client for the HuBMAP Cells API; See also: cells-api-js-client.

Contributors start here.

Usage

Install from pypi:

pip install hubmap-api-py-client

Find cells with different criteria, and intersect resulting sets:

>>> from hubmap_api_py_client import Client
>>> client = Client('https://cells.dev.hubmapconsortium.org/api/')

>>> [m for m in dir(client) if m.startswith('select_')]
['select_cells', 'select_clusters', 'select_genes', 'select_organs']

>>> cells_with_vim = client.select_cells(where='gene', has=['VIM > 0.5'], genomic_modality='rna')
>>> assert len(cells_with_vim) > 0

# Select cells from the datasets with the following UUIDs:
>>> dataset_a_uuid = '68159e4bd6a2cea1cd66e8f3050cfcb7'
>>> dataset_b_uuid = 'e8d642084fc5ec8b5d348ebab96a4b22'
>>> cells_in_a_len = len(client.select_cells(where='dataset', has=[dataset_a_uuid]))
>>> cells_in_b_len = len(client.select_cells(where='dataset', has=[dataset_b_uuid]))
>>> cells_in_datasets = client.select_cells(where='dataset', has=[dataset_a_uuid, dataset_b_uuid])
>>> cells_in_datasets_len = len(cells_in_datasets)
>>> assert cells_in_datasets_len > 0
>>> assert cells_in_datasets_len == cells_in_a_len + cells_in_b_len

# Combine criteria with intersection:
>>> cells_with_vim_in_datasets = cells_with_vim & cells_in_datasets

# Get a list; should run quickly:
>>> cell_list = cells_with_vim_in_datasets[0:10]
>>> assert len(cell_list) == 10
>>> assert cell_list[0].keys() == {'cell_id', 'modality', 'dataset', 'clusters', 'protein_mean', 'protein_total', 'protein_covar'}

More examples

Only some types of objects can be retrieved from other types of objects:

• "✓" = Supported by Cells API, and this client.
• "✶" = Supported by Entities API; support in this client is on the roadmap.
• "✩" = Possible connection to ASCT-B (Anatomical Structures / Cell Types / Biomarkers)
