abstract = {We present a generative model, Lux, to quantify DNA
methylation modifications from any combination of bisulfite
sequencing approaches, including reduced, oxidative,
TET-assisted, chemical-modification assisted, and
methylase-assisted bisulfite sequencing data. Lux models all
cytosine modifications (C, 5mC, 5hmC, 5fC, and 5caC)
simultaneously together with experimental parameters,
including bisulfite conversion and oxidation efficiencies,
as well as various chemical labeling and protection steps.
We show that Lux improves the quantification and comparison
of cytosine modification levels and that Lux can process any
oxidized methylcytosine sequencing data sets to quantify all
cytosine modifications. Analysis of targeted data from
Tet2-knockdown embryonic stem cells and T cells during
development demonstrates DNA modification quantification at
unprecedented detail, quantifies active demethylation
pathways and reveals 5hmC localization in putative
regulatory regions.},
