# DRAGEN Array Methylation QC Cloud v1.0.0 Release Notes

## RELEASE DATE

May 2024

## RELEASE HIGHLIGHTS

* Adjustable thresholds to determine pass/fail status
* Data summary plots for a quick visual check of each analysis batch
* Determining detection p-value, beta-values, and m-values from each methylation sample
* Deployment on BaseSpace™ Sequence Hub user interface for easy analysis kickoff

## NEW FEATURES IN DETAIL

* Adjustable thresholds for 21 built in controls, p-value detection, proportion probes passing, and offset correction within BaseSpace Sequence Hub to customize for user’s study needs
  * Thresholds are used to assign pass (1) or fail (0) status to each sample
    * Failed metrics can be highlighted for easy viewing
  * Pinpoint areas of failure including bisulfite conversion, staining, hybridization, etc. to identify assay steps in need of troubleshooting
  * Quantitative values for each control removing ambiguity with manual interpretation
* Data summary plots with information on passing p-value detection and principal component analysis of beta values
* Provides detection p-value, beta-values and m-values for each CG site per sample to use in downstream analysis

## KNOWN ISSUES

## KNOWN LIMITATIONS

* Standard thresholds may not be applicable for all discontinued, semi-custom or custom BeadChips and IDATs originating from NextSeq550
* Built-in controls may not be available on all discontinued, semi-custom or custom BeadChips

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.connected.illumina.com/dragen-array/dragen-array-v1.2/reference/release-notes/dragen-array-v1.0.0-release-notes/dragen-array-v1.0.0-cloud-methylqc-release-notes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
