How to access EMMA for MGE members

• Refer to the MGE homepage to find out if your institution is a member.
• 1) Login to the Portal:
  • If you are a MGE member you should have a login and password for the MGE bioinformatics portal. Your login is usually as follow: Firstname_Surname.
  • Forgot your password? If you have a login to access the MGE bioinformatics portal and have forgotten your password, you can use the following form to submit a password change request.
  • If you don't remember your login, please send a email to mg-bielefeld[at]cebitec.uni-bielefeld.de
• 2) Access to a EMMA project:
  • Once you have logged into the MGE Bioinformatics portal, please check if you can already access a EMMA project by clicking on the link "My Projects" in the Action menu. For more info, have a look at this link.
  • If you don't have access to a EMMA project, either you can have a look at the Demo project or you can request access to a MGE project. The procedure is explained under this MGE wiki link and this GPMS wiki link.
  • Depending on your privileges for the EMMA project(s) you can access, the tasks you can perform inside a EMMA project can be limited. More info can be found under this EMMA guideline Rights and Roles page.
• 3) Use ArrayLIMS and EMMA with your own data:
  • The best is to have your own project as chief. For that you need to request a New Project inside the MGE Bioinformatics Portal. The procedure is explained under this MGE wiki link.
  • Once you have access to your project, please read the ArrayLIMS and EMMA documentations before to start to use EMMA.
