What data format does this skill require?

The scvi-tools skill primarily works with AnnData objects and requires unnormalized raw count data for optimal performance in its probabilistic models.

How does it handle batch effects?

It uses variational autoencoders and registered covariates during setup to learn latent representations that are automatically corrected for technical variations across different batches or studies.

Does scvi-tools support GPU acceleration?

Yes, the skill provides implementation patterns for utilizing PyTorch Lightning's GPU support to significantly accelerate model training on large datasets.

Can I use this for spatial transcriptomics?

Absolutely. It includes specific models like DestVI and Stereoscope for spatial deconvolution and mapping cell types to spatial locations.
