# Welcome

### About the Our Future Health research programme <a href="#about-the-our-future-health-research-programme" id="about-the-our-future-health-research-programme"></a>

We’re bringing together data from up to 5 million adults in the UK. Registered researchers can request access to this data and analyse it to discover new ways to prevent, detect and treat diseases.

The programme aims to provide two main resources for health research:

* an observational dataset for basic science, epidemiological discovery and aetiological research
* a cohort of participants who can be contacted for translational research

Find out more about our programme in the [Cohort Profile: Our Future Health](https://doi.org/10.1093/ije/dyaf171) publication in the International Journal of Epidemiology (Volume 54, Issue 6, December 2025) or have a look on the [Programme design and recruitment](/our-future-health/programme/programme-design-and-recruitment.md) page.&#x20;

### About the Our Future Health Trusted Research Environment (TRE)

The Our Future Health Trusted Research Environment (TRE) is built on the DNAnexus Platform. You can access information about the DNAnexus platform in the [DNAnexus documentation](http://documentation.dnanexus.com/).

Visit the [TRE documentation](https://dnanexus.gitbook.io/ofh) for end-to-end guidance on working within the Our Future Health TRE, covering user onboarding, governance, and secure access requirements alongside practical instructions for using the platform. It details how to discover and extract cohort data, run analyses via tools such as Jupyter notebooks or command line interfaces, and manage files through controlled mechanisms like the Airlock. It also includes operational and technical reference material, such as environment structure, permissions, and best practices, so researchers can reproducibly and securely conduct analyses within the TRE.

Visit our public [github](https://github.com/ourfuturehealth/tre-example-notebooks) repository for example code scripts in the form of interactive Python notebooks (`.ipynb`), inlcuding python, R and bash notebooks, to help you get started with the resource.

# 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://ourfuturehealth.gitbook.io/our-future-health/welcome.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.
