LIANA+: an all-in-one cell-cell communication framework

LIANA+ is a scalable framework that integrates 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, and relies on AnnData & MuData objects as input.

Development & Contributions

We welcome suggestions, ideas, and contributions! Please use do not hesitate to contact us, open issues, and check the contributions guide.

Vignettes

A set of extensive vignettes can be found in the LIANA+ documentation.

Decision Tree

Q: Does the data contain spatial coordinates?

Yes

• Q: Bivariate or unsupervised, multi-variate, and multi-view analysis?
  • Bivariate:
    • Q: Are you interested in identifying the subregions of interactions (i.e., local interactions)?
      • Yes: Check the Local Bivariate Metrics
      • No: Check the Global Bivariate Metrics
  • Unsupervised: Multi-view learning

No

• Q: Are you interested in comparing CCC across samples?
  • Yes:
    • Q: Are you interested in a specific contrast?
      • Yes: Differential Contrasts and Downstream Signalling
      • No: Unsupervised Cross-conditional LR inference with MOFA+ or Tensor-cell2cell
  • No: Steady-state Ligand-Receptor inference

Is your data Multi-modal?

• Spatial: Integrating Multi-Modal Spatially-Resolved Technologies
• Non-Spatial: Integrating Multi-Modal Single-Cell Technologies
