Q (sonnet): Can you find a study that I may emulate that has a data_clinical_outcomes.txt file and associated meta file to interogate

═ answer (success)
This request is about the underlying file structure of cBioPortal study packages (data/meta files), which isn't something my database query or navigation tools track directly — the ClickHouse database stores parsed clinical/genomic data, not the raw file manifest of each study's download package. Let me check what I can find, and clarify what "emulate" likely means here.

A `data_clinical_outcomes.txt` file (paired with `meta_clinical_outcomes.txt`) is a **non-standard, study-specific supplementary file** — it's not part of the standard cBioPortal file spec (which defines `data_clinical_patient.txt`, `data_clinical_sample.txt`, `data_timeline_*.txt`, etc.). It shows up in specific study packages (often MSK studies) that included curated outcome-event data beyond the standard timeline format.

I don't have a tool that scans raw file listings across all ~400+ studies for that exact filename — my database access is to parsed clinical/genomic data, not the original file bundles. However, I can point you to where to check directly:

1. **cBioPortal Datahub (GitHub)** — the canonical place raw study files live: [https://github.com/cBioPortal/datahub](https://github.com/cBioPortal/datahub). You can search the repo directly for `data_clinical_outcomes.txt`:
   [github.com/search?q=repo%3AcBioPortal%2Fdatahub+data_clinical_outcomes&type=code](https://github.com/search?q=repo%3AcBioPortal%2Fdatahub+data_clinical_outcomes&type=code)

2. If you already have a specific study in mind that you recall having this file, tell me the name and I can pull up its full clinical/molecular profile and guide via the study guide tool, and confirm what clinical attributes it exposes in the database (which would reflect the contents of that outcomes file, since cBioPortal ingests it into clinical attributes at load time).

Could you clarify what you mean by "emulate" here — are you looking for:
- A study to use as a **template file structure** for building your own study package (i.e., you want to see the format cBioPortal expects), or
- A **similar disease cohort** whose analysis approach you want to replicate?

If it's the former, I'd point you to the [Datahub file format docs](https://docs.cbioportal.org/file-formats/) rather than a specific study, since `data_clinical_outcomes.txt` isn't part of the documented standard — it may be a locally-defined file at whichever institution created it.
