Terra workspaces integrate data, analysis tools, and built-in security components to deliver smooth research flows from data to results. The following entries in this section of the BDC documentation are a starting point for learning how to use Terra in the context of the BDC ecosystem. You can also dive deeper into Terra by visiting the [Terra website](https://terra.bio/) and the [Terra Support Center](https://support.terra.bio/). Wherever possible, we highlight specific articles, tutorial videos, and example workspaces that will help you learn what you need to know to accelerate your research. If you can't find what you are looking for, we are happy to help. See the Troubleshooting and Support section for more information. Please note that Terra is designed for and tested with the [Chrome](https://www.google.com/chrome/) browser. --- # 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://bdcatalyst.gitbook.io/biodata-catalyst-documentation/written-documentation/analyze-data-1/terra.md?ask=&goal= ``` `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.
