The HCA Biological Networks are members of the Human Cell Atlas community who are creating comprehensive reference maps of human cells from specific tissues, organs, organ systems, or other biological areas as part of the greater effort of building a human cell atlas. In this guide, you will learn how to find, explore, and download data that is associated with each Biological Network and Atlas from the HCA Data Explorer.
The HCA Data Portal HCA BioNetworks page lists all of the HCA Biological Networks along with the number of atlases that are associated with each. Some Biological Networks may have multiple atlases that are different versions of a single atlas or atlases dedicated to different tissues of interest.
Selecting a Biological Network takes you to its overview page.
On the Biological Network Overview page, you will find:
If the atlases for a Biological Network are still in development, the Biological Network Overview page will have a * Datasets* tab where you can browse HCA projects that contain data from tissues of interest for that Biological Network.
From a Biological Network Overview page, selecting the name of an atlas takes you to an overview of the atlas.
The atlas Overview page contains:
To see all projects in an atlas, select the Source Datasets tab on the atlas’s Overview page.
By selecting a project title on the list of datasets associated with a Biological Network or atlas, you can find project information and links to download project metadata and matrices. See Exploring Projects to learn more.
