Description

Hi

After I performed ingest, I need to concatenate the two datasets. But when followed the tutorial, used concatenated but this function doesn't;t concatenate the .obsm, therefore the UMAP coordinates are not merged. How did you manage to performed UMAP on the integrated/concatenated dataset?

Research direction

Start by reviewing the tutorial's concatenation workflow and reproducing what happens to .obsm and the UMAP coordinates after ingest. No source file or test is named, so locate the concat entry point and related tests before deciding whether the expected behavior is a code change or documentation clarification; done means the behavior and the UMAP workflow are explicitly verified.
