Getting Started with MD.ai Annotator

Learn the basics of using MD.ai Annotator to get all your deep learning projects up and running. This document covers signing up, recommended browser, opening assigned cases, and troubleshooting.

Signing Up

Please follow the directions to get started:

Go to https://www.md.ai and click on the 'Sign up' button.

Identity Providers

You can sign up using your Google account, Github account, or use your email address. Important: If you've gotten an email invitation to a project, make sure to use that email to sign in. If you get an error message after signing in,double check the invitation email.

Signing In

If you've gotten an email invitation to a project, just click on the link for access. Make sure to use the email from the invitation to sign in. For example, if you got an invitation to your .edu address and you try to sign in with your gmail account, you won't be granted access. Signing in with the correct email will open the project and your cases.

Browser

Annotator is an HTML5 web application optimized for the latest Google Chrome browser. We highly recommend using Chrome on a laptop/desktop.

Chrome

Annotator has been most extensively tested on MacOS, ChromeOS, and Ubuntu Linux, and we recommend at least 4GB of RAM.

Annotation on mobile devices is not supported but may be sufficient for global annotation. Mozilla Firefox has not been tested, but should probably work.

Your cases will be loaded automatically

Choose the appropriate dataset in the dropdown menu if there is more than one, eg. training and validation datasets

Troubleshooting

  • Can't click on labels - Make sure you are signed in otherwise you are in view only mode.
  • Polygon drawing doesn't draw what I want - Make sure you are using a computer (not a mobile device) and that you are using the Chrome Browser
  • Other unexpected behavior - restart Chrome and if problem persists, please let us know with the Feedback button in the Navigation Tag of the Annotator
  • Signed in with email but I'm getting an error message - Make sure you are using the correct email. If you got an invitation link, double check the invite email
