Introduction ============ Welcome to the Nico Documentation! NiCo ( **Ni** che **Co** variation) is a tool designed for the comprehensive analysis of imaging- and sequencing-based spatial transcriptomics data. This documentation provides detailed instructions on how to use the tool, including installation, usage examples, and API references. Key Features: ------------- - **Cell Type Annotation:** Accurate annotation of cell types in the spatial modality by label transfer. - **Visualization of Cell Types in Space:** Generation of UMAP plots and spatial maps to visualize cell types. - **Spatial Neighborhood Analysis:** Identification and analysis of cell type-cell type interactions within spatial niche neighborhoods. - **Inference of Cell State Covariation:** Analysis of molecular crosstalk of cell types co-localized in niches using latent variable regression. - **Visualization of Ligand-Receptor Pairs:** NiCo visualizes ligand-receptor pairs associated with covarying latent variables of interacting cell types. - **Visualization of Pathways:** NiCo visualizes enriched pathways in the top correlating genes associated with latent variables. Getting Started: ---------------- To get started with NiCo, follow the installation instructions and refer to the examples and tutorials for detailed examples. Github Tutorials: ---------------- The tutorials in Jupyter notebook format for finding covariation in selected colocalized cell type are `available here, `_ and the Python scripts for finding the covariation in all colocalized cell types is `available here. `_ Contributing: ------------- We welcome contributions to the project. If you would like to contribute, please refer to the contributing guidelines. Support: -------- For support, please check the FAQ section.
