# Methylation Clock

Read biological age off a methylation array

## What this does

You have DNA methylation array data and you want the epigenetic age that comes out of it. This computes that, taking either a public accession or a file you already have. Reach for it when the arrays exist and the age estimate is what you are after.

### Top 3 things it does for you

- Compute epigenetic age from methylation data
- Work from a GEO accession or a local file
- Apply PyAging clocks to your arrays

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## Questions

### Is Methylation Clock safe to install?

AIR scanned this exact version of Methylation Clock and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 5ae5a62b9c7b, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/methylation-clock.

### How do I install Methylation Clock?

Open https://airmarket.ai/app/methylation-clock on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/ClawBio/ClawBio/tree/5ae5a62b9c7ba223fc71c923718bbc320e181afa/skills/methylation-clock. Install from that link, not the branch.
