# How to Format a Sample Sheet for a GenomeStudio Methylation Project - Support Video

This video provides a step-by-step overview of how to correctly format a sample sheet for creating an Infinium methylation array project in GenomeStudio v2011.1 using the Methylation Module. It explains the key components of a sample sheet, including required and optional columns, and highlights common formatting requirements to ensure successful project setup.

The video also demonstrates where to download approved sample sheet templates. It also outlines best practices for formatting the sample sheet, including proper format of sample identifiers, plate and position information, and BeadChip barcode formatting to minimize errors and ensure smooth analysis.

In addition, the video outlines strategies for optimizing sample sheet configuration to improve processing efficiency and reduce analysis time within GenomeStudio. Finally, it provides a walkthrough of how the formatted sample sheet is used during project creation, illustrating how the information is imported and applied within the GenomeStudio methylation workflow.

# 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://knowledge.illumina.com/microarray/genomestudio/microarray-genomestudio-reference_material-list/000007124.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.
