xcltk: Toolkit for XClone Preprocessing

XClone is a statistical method to detect allele- and haplotype-specific copy number variations (CNVs) and reconstruct tumour clonal substructure from scRNA-seq data, by integrating the expression levels (read depth ratio; RDR signals) and the allelic balance (B-allele frequency; BAF signals). It takes three matrices as input: the allele-specific AD and DP matrices (BAF signals) and the total read depth matrix (RDR signals).

The xcltk package implements a preprocessing pipeline to generate the three matrices from SAM/BAM/CRAM files. It supports data from multiple single-cell sequencing platforms, including droplet-based (e.g., 10x Genomics) and well-based (e.g., SMART-seq) platforms.

Installation

Install via pip (latest stable version)

xcltk is avaliable through pypi.

pip install -U xcltk

Install from this Github Repo (latest stable/dev version)

pip install -U git+https://github.com/hxj5/xcltk

In either case, if you don't have write permission for your current Python environment, we suggest creating a separate conda environment or add --user for your current one.
