## Differentially Methylated Genes
This package aims to consolidate DMRs (differentially methylated regions) and DMCs (differentially methylated cytosines)
and most importantly, develop a consistent, **unbiased** method for assigning a change in DNA methylation to a gene.
See the [docs](https://arianemora.github.io/scidmg/) for detail.

The user provides a DMR file, a file with the percentage of DNA Methylation, and also the DMCs. Using these, sci-DMG
consolidates the DMR's and DMC's that are consistent. DMR regions (significant q <= 0.1) with at least 60% of DMCs
(q < 0.1) agreeing with the DMR change in methylation direction were kept.
Genes with multiple DMRs were removed if the DMRs were not in agreement (meth. Diff. direction).
If the DMRs were in agreement, the CpG with the highest DNA methylation difference in the direction of change is
assigned as the methylation value (change and padj) for that gene i.e. as the driver CpG behind the gene’s change in
DNA methylation. Note the cutoff values are all adjustable.

Any tool can be used to produce the DMC's and DMR's, two such tools are
[MethylKit](https://bioconductor.org/packages/release/bioc/html/methylKit.html) and
[MethylSig](https://pubmed.ncbi.nlm.nih.gov/24836530/) many others exist.

**Note:** The CpGs and DMRs must have already been assigned to genes, this tool consolidates the DMRs and DMCs after
they have been assigned to genes.
