Look up markers with auto-complete:
markers = bt.CellMarker.lookup()
markers.cd8
CellMarker(uid='5YxpB5QNiCWr', name='CD8', synonyms='', gene_symbol='CD8A', ncbi_gene_id='925', uniprotkb_id='P01732', updated_at=2024-03-28 12:12:01 UTC, organism_id=1, public_source_id=18, created_by_id=1)
Query artifacts by markers #
Query panels and collections based on markers, e.g., which collections have 'CD8' in the flow panel:
panels_with_cd8 = ln.FeatureSet.filter(cell_markers=markers.cd8).all()
ln.Artifact.filter(feature_sets__in=panels_with_cd8).df()

file1, file2 = artifacts[0], artifacts[1]
shared_markers = file1.features["var"] & file2.features["var"]
