Copy-number Aware Methylation Deconvolution Analysis of Cancer (CAMDAC) is an R library for deconvolving pure tumor methylation from bulk tumor sequencing data (Larose Cadieux et al., 2022, bioXriv).
This branch performs CAMDAC analysis for whole genome bisulfite sequencing (WGBS) data. For Reduced Representation Bisulfite Sequencing (RRBS) data analysis, visit the VanLoo-lab/CAMDAC main branch.

CAMDAC can be installed from an R console:
remotes::install_github("VanLoo-lab/CAMDAC@wgbs")
CAMDAC::download_pipeline_files("wgbs", directory = "./refs")To run the tumor-normal deconvolution pipeline:
library(CAMDAC)
# Get test data
tumor_bam = system.file("testdata", "tumor.bam", package = "CAMDAC")
normal_bam = system.file("testdata", "normal.bam", package = "CAMDAC")
# Run pipeline
tumor = CamSample(id="T", sex="XY", bam=tumor_bam)
normal = CamSample(id="N", sex="XY", bam=normal_bam)
config = CamConfig(outdir="./results", bsseq="wgbs", lib="pe", build="hg38", refs="./refs", n_cores=10)
CAMDAC::pipeline(tumor, germline=normal, infiltrates=normal, origin=normal, config)For a more detailed walkthrough, see vignette("pipeline").
