# FinnGen Data Freezes and Releases

During the active sample collection phase (years 2017-2023), the **Data Freeze (DF)** happened twice a year in February and August. At these times, FinnGen produced **Data Release (R)** of updated genotype and phenotype data files to the Sandbox.

During FinnGen 3 (Aug 2023 onwards) the sample size is fixed and Data Releases focus on updating health register data. Three releases are planned: R13 (February 2025), R14 (February 2026), and R15 (February 2027).

### Following data files are released to Sandbox per each Data Freeze/Release

* [Genotype files](/finngen-data-specifics/red-library-data-individual-level-data/genotype-data/types-of-genotype-files-available.md)
* [Phenotype files](/finngen-data-specifics/red-library-data-individual-level-data/what-phenotype-files-are-available-in-sandbox-1.md)
* [other registry data files ](/finngen-data-specifics/red-library-data-individual-level-data/what-phenotype-files-are-available-in-sandbox-1/other-registers.md)(periodically updated and released to Sandbox)
* [Core Analysis Results files ](/finngen-data-specifics/green-library-data-aggregate-data/core-analysis-results-files.md)(released to FinnGen Production Library Green per each Data Release)

All data and core analysis result releases are announced via the finngen-accounts mailing list and at the [FinnGen Science and Users' ](/user-support.md)meetings. You can also find the releases in the Handbook [Release notes](/release-notes.md).

**Note on data availability after release:**

When new genotype and phenotype files are first released, please be aware of the following timeline:

* **Month 1:** The analysis team generates covariate files needed for GWAS. You will not be able to run GWAS until these are ready.
* **Months 1-3:** The register and phenotype teams update all [other register data](/finngen-data-specifics/red-library-data-individual-level-data/what-phenotype-files-are-available-in-sandbox-1/other-registers.md) (not included in the detailed longitudinal data and endpoints) release them to Sandbox. Most of these are also converted to OMOP format and made available to the various analysis tools in the Sandbox.
* **Month 3:** The analysis team releases a set of so-called core analysis results to the [Google Cloud storage green bucket](/finngen-data-specifics/green-library-data-aggregate-data/how-can-you-download-green-data.md) (`gs://finngen-production-library-green`). These analyses include, but are not limited to, GWAS summary statistics, fine-mapping, colocalization, and autoreporting results.

**Bottom line:** It takes approximately 2-3 months after the initial release before all data and analysis tools are fully updated.
