nico-gruenlab 1.3.0

This package finds covariation patterns between interacted niche cell types from single-cell resolution spatial transcriptomics data.

NiCo: Niche Covariation Analysis

Developed by Ankit Agrawal (c) Grün lab 2024

NiCo package designed to uncover covariation patterns between interacting cell types from image-based single-cell resolution spatial transcriptomics data. It enables comprehensive cell type annotations, niche interaction discoveries, and the analysis of covariation patterns between interacting cell types.

Key Features

• Cell Type Annotation: Perform accurate cell type annotations on single cell resolution spatial transcriptomics data.
  
• Niche Interaction: Identify and analyze colocalized interactions between different cell types within their tissue niches.
  
• Covariation: Discover covariates between colocalized cell types to understand the cross-talk of gene modules and the enrichment of pathways in the niche.

Installation

Install the NiCo package using the conda environment. This ensures all dependencies are correctly managed and installed.

conda create -n nicoUser python=3.11
conda activate nicoUser
pip install nico-sc-sp
pip install jupyterlab

Sometimes, the pygraphviz package cannot be installed via pip, or during the cell type interaction part, it gives an error that "neato" is not found in path, so an alternative conda way of installation is recommended. Please follow the installation of pygraphviz here

conda create -y -n nicoUser python=3.11
conda activate nicoUser
conda install -c conda-forge pygraphviz
pip install nico-sc-sp
pip install jupyterlab
