/opt/hostedtoolcache/Python/3.10.14/x64/lib/python3.10/site-packages/anndata/_core/anndata.py:1818: UserWarning: Observation names are not unique. To make them unique, call `.obs_names_make_unique`.
  utils.warn_names_duplicates("obs")

The AnnData has the reference to the individual files in the .obs annotations:

adata.obs.artifact_uid.cat.categories

Index(['mk6q3qCTNYXBVz0vaqcz', '6iPyp7YLY9fnKHWtXcks'], dtype='object')

By default, the intersection of features is used:

adata.var.index

Index(['CD8', 'CD27', 'Ccr7', 'Cd4', 'CD45RA', 'CD3'], dtype='object')

Let us create a plot:

markers = bt.CellMarker.lookup()

import scanpy as sc

sc.pp.pca(adata)
sc.pl.pca(adata, color=markers.cd8.name, save="_cd8")

WARNING: saving figure to file figures/pca_cd8.pdf

artifact = ln.Artifact("./figures/pca_cd8.pdf", description="My result on CD8").save()
artifact.view_lineage()

Given the image is part of the notebook, there isn’t an actual need to save it and you can also rely on the report that you’ll create when saving the notebook:

ln.finish()

# clean up test instance
!lamin delete --force test-facs
!rm -r test-flow
