Getting Started: Finding Data in Flywheel
Welcome to Flywheel
If you are new to using Flywheel, you may have been given access to a dataset by a collaborator. This tutorial will walk you through the basics of finding and viewing your data in Flywheel.
What You Will Learn
By the end of this tutorial, you will understand:
- How to sign in to Flywheel
- Where your data is located in the platform
- Two different methods for finding data
- How to view images using the Flywheel viewer
Before You Begin
You need:
- Access to your institution's Flywheel site
- A Flywheel account created by your site administrator
- Permission to at least one project
Do not see any projects?
Your site admin needs to give you permission to a project to be able to view it. Contact your site administrator if you do not have access.
Step 1: Sign In to Flywheel
-
In your browser, go to your institution's Flywheel site. For example:
https://University.Flywheel.io
-
Sign in to Flywheel using the email your site administrator used to create your account.
-
Once you are signed in, your Flywheel projects appear. Flywheel projects contain the information and data used in studies and trials.
Step 2: Understand How Flywheel Organizes Data
Flywheel organizes data in a hierarchical structure:
- Projects contain all data for a study or trial
- Subjects represent individual participants in a study
- Sessions represent a single visit or exam (for example, one time in the MRI scanner)
- Acquisitions contain the actual image files
- Files are the individual data files (DICOM, NIFTI, etc.)
Where are my images?
Flywheel places images under Acquisitions. Each acquisition represents one series or sequence from an imaging session.
To learn more about how Flywheel organizes data, see The Flywheel Hierarchy.
Step 3: Find Your Data
There are two main ways to locate data in Flywheel:
Method 1: Use Search
Search is useful when you do not know exactly which project contains your data, or when you want to find data across multiple projects.
-
Type a search term in the Search Box on the left sidebar
See all your data
Hit enter on the blank search bar to bring up all data you have access to in Flywheel.
-
Use the filters to narrow down the data you are looking for. For example, if you know you uploaded the data within the last few days, go to Session Timestamp, and adjust the range.
Flywheel searches across all projects you have permissions to access. Because Flywheel search uses fuzzy matching, you only need to know a little bit of information about the data to find what you are looking for.
Method 2: Navigate Through Projects
If you know which project contains your data, you can navigate directly to it:
-
Click on a Project from your dashboard.
The Project description page appears.
-
Click the Sessions tab in the top menu.

The Sessions tab shows each subject's visit or exam performed for the project.
Group data by subject
To organize the data in your project by subject instead of session, click Subject View
. -
Select a session.
All images associated with that subject and project appear in the acquisitions tab.
Step 4: View an Image
Now that you have found your data, you can view images to check quality or verify correct upload.
From Search Results
- Click the Files tab in your search results
- Select the action menu and select view

From a Session
-
Hover over an acquisition. The image icon (
) appears.
-
Click
.
The viewer opens with the image series. The Flywheel viewer allows you to annotate and report on images in 2D (slices).
What You Have Learned
You now know how to:
- Sign in to Flywheel and access your projects
- Understand how Flywheel organizes data hierarchically
- Find data using search or project navigation
- View images using the Flywheel viewer
