I want to perform batch integration on multiple datasets (loaded as separate h5ad files). Is there an exemplar code snippet on how to do this?

Once I’ve loaded and pre-processed the data, what is the best way to rigorously perform hyperparameter tuning of the scVI model?

For concatenating and integrating multiple datasets, please refer to [this tutorial](https://docs.scvi-tools.org/en/stable/tutorials/notebooks/scrna/tabula_muris.html) that combines two datasets.

For an example on how to perform hyperparameter tuning with scVI, please refer to [this tutorial](https://docs.scvi-tools.org/en/stable/tutorials/notebooks/tuning/autotune_scvi.html)
