Query artifacts

Here, we’ll query artifacts and inspect their metadata.

This guide can be skipped if you are only interested in how to leverage the overall collection.

Compare features

Here we compute shared genes:

artifact1_genes = artifact1.features["var"]
artifact2_genes = artifact2.features["var"]

shared_genes = artifact1_genes & artifact2_genes
len(shared_genes)

749

shared_genes.list("symbol")[:10]

['HES4',
 'TNFRSF4',
 'SSU72',
 'PARK7',
 'RBP7',
 'SRM',
 'MAD2L2',
 'AGTRAP',
 'TNFRSF1B',
 'EFHD2']

Compare cell types

artifact1_celltypes = artifact1.cell_types.all()
artifact2_celltypes = artifact2.cell_types.all()

shared_celltypes = artifact1_celltypes & artifact2_celltypes
shared_celltypes_names = shared_celltypes.list("name")
shared_celltypes_names

['CD4-positive helper T cell',
 'CD16-positive, CD56-dim natural killer cell, human']

Load the individual artifacts

We could either load the artifacts into memory or access them in backed mode through .open() to lazily load their content.

Let’s load them into memory:

adata1 = artifact1.load()
adata2 = artifact2.load()

We can now subset the two collections by shared cell types:

adata1_subset = adata1[adata1.obs["cell_type"].isin(shared_celltypes_names)]
adata2_subset = adata2[adata2.obs["cell_type"].isin(shared_celltypes_names)]
