Using the site
Quick start: login as the default user "predikin" using the form on the left, then go to submit a kinase in the Predikin menu.

If you want to use Predikin regularly, you should register and create a username and password. You will then receive a confirmatory email with a link to activate your account.
The results of your predictions are linked to your username, so we recommend that you create an account if you intend to use Predikin regularly.
Note that if more than one user is logged in as the default "predikin" user, it will be difficult to see which predictions belong to you.
