     "We refer to this *asymmetric* dataset integration as *ingesting* annotations from an annotated reference `adata_ref` into an `adata` that still lacks this annotation. This is different from learning a joint representation that integrates datasets in a symmetric way as [BBKNN](https://github.com/Teichlab/bbknn), MNN, Scanorma, Conos, CCA (e.g. in Seurat) or a conditional VAE (e.g. in scVI, trVAE) would do. Take a look at tools in the [external API](https://scanpy.readthedocs.io/en/latest/external/#data-integration) or at the [ecoystem page](https://scanpy.readthedocs.io/en/latest/ecosystem/#data-integration) to get a start with other tools.\n",
