NIAGADS GWAS Data

To access NIAGADS GWAS data, navigate to the ADGC & NIAGADS Dashboard.

1. Select the data type you wish to access.

   If the card is grayed out, that means you do not have access to the corresponding Flywheel project. Contact your center's administrator or director to request access.

2. Each card will bring you to the corresponding data type's landing page, which lists the files available for your center along with a brief summary about the data and how it was generated. The data for each genotyping round is contained in a tar.gz archive.

3. To download the data, click on one of the download icons next to the data files, which will bring up the downloads dialogue for that specific file.

4. Click on the "Generate Download Link" button. This generates a download link that expires in 24 hours. Clicking on the link will start the download process for that specific file.

   Due to the size of the data, some files may take a long time to download. Be sure to double check the size of the archive before downloading.

5. Once the file is downloaded, you will need to extract the individual files from the archive. The easiest way to do that is in a terminal with the tar command, replacing filename.tar.gz with the name of your file.
   1. For machines where a terminal is not easily accessible, or a GUI is preferred, you can also use a third-party file archiver such as 7-Zip or WinZip.

tar xzf filename.tar.gz

The above will extract the contents to the same directory. To extract to a specific directory, use the -C flag:

tar xzf filename.tar.gz -C path/to/target/dir
