Hi Shawn and Bradley - following on from today’s discussion, I’d really like to be able to do a side by side comparison of metadata on the same single cell datasets from multiple platforms:
HCA data portal https://data.humancellatlas.org/explore/projects/celltype.infohttps://cellxgene.cziscience.com/collectionsAzimuth (although still not very much on there)
Allen Brain Atlas (can we download matrices directly from there) / Nemo
Problem - finding candidate sets to compare. We should have one brain and one-non-brain. Non-brain should be something with some detailed annotation.
Brain - should probably be mini-atlas. Challenge might be dataset size.
Non-brain. Kidney might be good, although struggling to find example (CAP needs to show publication!)
What to compare:
Keys used for standard metadata
How ontologies are supported
How cell type is recorded - what, if anything is lost in flattening
Relationship metadata content to display on site.
