DANDI Client

The DANDI Python client allows you to:

• Download Dandisets and individual subject folders or files
• Validate data to locally conform to standards
• Organize your data locally before upload
• Upload Dandisets
• Interact with the DANDI instance's web API from Python
• Delete data in the DANDI instance
• Perform other auxiliary operations with data on the DANDI instance

Note: This project is under active development. See the issues log or Work-in-Progress (WiP).
