Downloading Data

There are several options for getting data out of Flywheel to analyze or share it. The best option to use depends primarily upon these factors:

  1. Volume of data
  2. Type of destination (Cloud Storage, Local Computer, etc.)

Small Batch Download

If you are downloading a few sessions or acquisitions, you can download them directly from your project as a ZIP archive. For step-by-step instructions, see Downloading Sessions or Acquisitions from the Web UI.

Selecting sessions and choosing file types to download

You can also download an individual acquisition or file from its options menu (). See Downloading a File from the Web UI.

Full Project Download

Use Download Project (the download icon in the project toolbar) to export a full project, including metadata and analyses, from Flywheel to your computer as a ZIP archive. This method keeps data in the Flywheel hierarchy structure. For step-by-step instructions, see Downloading an Entire Project from the Web UI.

Large Projects

This option is best used for smaller projects. For projects containing large volumes of data, consider using the Bulk Export option instead.

Large Volumes of Data

If you have many scans in your project, you can use the Bulk Export feature to download large amounts of data to an External Storage location.

Tip

Bulk Export is the recommended solution for exporting large volumes of data out of Flywheel and into an External Storage location.

If you cannot use an External Storage location and must download large amounts of data directly to your local computer, then you can use the fw sync command available via the Flywheel Command-Line Interface (CLI) to download the data instead.

Programmatic Downloads

If you need to initiate the download programmatically, you can use the following commands available in Flywheel's Command-Line (CLI) interface:

fw and flyw

Commands starting with flyw are available only in Flywheel's new CLI (flyw). The new CLI is a separate download and installation from Flywheel's legacy CLI (fw). For more information about the new CLI, go to https://flywheel-io.gitlab.io/tools/app/cli/flyw/.

Commands starting with fw are available only in Flywheel's legacy CLI (fw).

Instructions for downloading and installing both CLIs are available from within Flywheel Core Web App on your user profile page.
