In order to use the Metabolizer you need to be logged in. If you do not have an account, you can either create a new user for you or log in as an anonymous user.

1. If you want to log in as an anonymous user, click on Start.
2. If you already have an account, log in by clicking on Log in and giving your user and password.
3. If you want to create a new user, click on Sign up and fill in the form (all fields are required).

What difference is there between an anonymous user and a signed up user?

If you log in as anonymous user, you can access all the functionalities and tools of PathAct. However, all your work will be lost when you finish your session. If you create an account, you are given 10Gb of free disk space where you can save your data and results for future sessions.
