Dataset for "KnowYourCG: Facilitating base-level sparse methylome interpretation" --- hg38
Description
KYCG Knowledgebase Sets (hg38)
Overview
This repository contains comprehensive knowledgebase sets for the KnowYourCG (KYCG) framework, designed for functional DNA methylation analysis at base-level resolution. These databases enable rapid enrichment testing and interpretation of diverse methylation datasets, including sparse sequencing data (low-pass, single-cell), 5-hydroxymethylation (5hmC) profiles, spatial methylomes, and array-based EWAS datasets.
