FootprintCharter

Introduction

This vignette exemplifies how to perform unsupervised footprint detection and quantification using FootprintCharter as per Baderna & Barzaghi et al., 2024 and Barzaghi et al., 2024.

FootprintCharter partitions molecules by their methylation patterns without relying on orthogonal genomic annotations such as TF motifs.
