This article shows how to use "fw ls" command to navigate the Flywheel Hierarchy via CLI.
1. To start, enter fw ls
. This lists the groups available and their current permission levels.

2. Enter fw ls
again to look at projects assigned to a specific group.
Example: In this case we can check which projects have been assigned for ce-team group.
3. Further navigating the hierarchy we can see all subjects in a project and any files attached at project level and their time of upload.
Example: There are 9 subjects in project "Amygdala_Structure" and 1 attachment file.

4. One step further we can see sessions assigned to a particular subject and their timestamps.
Example: We have one session for subject amyg_s3:
![]() |
5. Last level is acquisitions. We can see acquisitions for each sessions.
![]() |
