Instructions
Load a built-in pycea example lineage-tracing dataset (downloaded on first use).
Great for demos and testing without your own data. Each returns a TreeData with a tree and (for most) expression, ready for plotting and heritability.
Datasets:
"packer19": C. elegans embryo lineage (option {"tree": "full"|"observed"}).
"yang22": mouse tumor phylogenies (option {"tumors": "3435_NT_T1"}).
"koblan25": prime-editing lineage tracing (option {"experiment": "tumor"}).
Args: name: One of packer19, yang22, koblan25. options: Keyword args forwarded to the pycea.datasets loader.
