LIANA+ is a scalable framework that adapts and extends existing methods and knowledge to study cell-cell communication in single-cell, spatially-resolved, and multi-modal omics data. It is part of the [scverse ecosystem](https://github.com/scverse), and relies on [AnnData](https://github.com/scverse/anndata) & [MuData](https://github.com/scverse/mudata) objects as input.

## Contributions

We welcome suggestions, ideas, and contributions! Please do not hesitate to contact us, open issues, and check the [contributions guide](https://liana-py.readthedocs.io/en/latest/contributing.html).

## Vignettes
A set of extensive vignettes can be found in the [LIANA+ documentation](https://liana-py.readthedocs.io/en/latest/).

## Decision Tree

Use the tree below to find a starting point for your analysis. Broad, data-driven choices sit at the top and trickle down to specific methods (click a node to open its tutorial).

This tree is a guide rather than an exhaustive map: the methods are modular and can be adapted or combined across data types and questions, and all of them typically build on curated prior knowledge (see the [prior knowledge](https://liana-py.readthedocs.io/en/latest/notebooks/prior_knowledge.html) tutorial for working with ligand–receptor and other resources).
