 # snp2cell
+
+snp2cell is a package for identifying gene regulation involved in specific traits and cell types.
+It combines three elements: (i) GWAS summary statistics, (ii) single cell data and (iii) a base gene regulatory network.
+A network propagation approach is used to integrate and overlap different types of scores on the network.
+Random permutations of scores are used to evaluate the significance of high scores. 
+A networkx graph of the gene regulatory network with integrated scores can be used to inspect gene regulatory programs that are linked to the trait (from GWAS) on a per cell type basis.
+
+## Installation
+
+```commandline
+mamba create -n snp2cell python<3.12
+mamba activate snp2cell
+
+
+```
