methylation-aggregation SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
methylation-aggregation from ammawla/encode-toolkit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ammawla/encode-toolkit/methylation-aggregation@git:20260921.7231da8Pins git:20260921.7231da8 in mdr.lock. Pin the fingerprint instead.

Build comprehensive DNA methylation maps by aggregating WGBS (Whole Genome Bisulfite Sequencing) data across multiple ENCODE experiments, donors, and labs. Use when the user wants to answer "where is DNA methylated/unmethylated in my tissue?" by combining per-CpG methylation data into tissue-level methylation profiles. Handles coverage filtering, identifies hypomethylated regions (HMRs) and partially methylated domains (PMDs), and manages cross-lab variation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Aggregate DNA Methylation Data Across Studies ## When to Use - User wants to build a tissue-level DNA methylation landscape from multiple WGBS experiments - User asks "where is DNA methylated in brain?" or "find hypomethylated regions across donors" - User needs to identify HMRs (hypomethylated regions), UMRs, or PMDs from aggregated WGBS data - User wants per-CpG weighted methylation averages from multiple experiments - Example queries: "aggregate WGBS data for liver", "build methylation map across donors", "find unmethylated CpG islands in pancreas" Build a comprehensive methylation landscape for a tissue/cell type by merging WGBS bedMethyl files from multiple ENCODE experiments. ## Scientific Rationale **The question**: "What is the DNA methylation state across the genome in my tissue?" DNA methylation is **fundamentally different** from histone marks and accessibility: | Property | Histone/Accessibility | DNA Methylation | |----------|----------------------|-----------------| | Signal type | Binary (bound/open or not) | Continuous (0-100% methylated) | | Default state | Unmarked | ~70-80% methylated (CpG context) | …

How to install
mdr add ammawla/encode-toolkit/methylation-aggregation@sha256:ac62a8738c77fc35The line at the top of this page pins the label git:20260921.7231da8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
