This package provides guidance for analysis of spatially resolved tissue (Visium ST), focusing on clonal dynamics derived from inferred copy number status.
Our particular goal has been identification of the "lethal clone", defined as the clone which metasises from primary cancer tissue to lymph nodes. However, this package can be used for any analysis of clonal evolution and/or somatic mosaicism in heterogeneous tissue.

This packages contains 4 major functions.
1 Infer Copy Number Variation based on transcriptomics data.
2 Spatial data wrapper.
3 Heatmap Plots.
4 Dendrogram selector.
This package is based on InferCNV & SpatialInferCNV. SPACEmapX is designed as a helper package for these.
