Getting started

Welcome to the first steps of the analysis framework documentation!

Let's start with some basics.

Are you a registered ALICE member?

Use this link to check if your CERN account is connected to ALICE. In case you see a message saying that you are not an ALICE member, you need to fix the problem: many services are not accessible if you are not considered an ALICE member.

Drop an email to the ALICE Secretariat, they will help you: alice.secretariat@cern.ch

Do you have access to lxplus?

When you have a CERN account you can typically login to lxplus via SSH:

ssh USERNAME@lxplus.cern.ch

If, in spite of providing the correct password, you are not allowed to connect, go on your CERN account management page. You need to Sign in and to select Resources and Services like in the picture below:

resources and services

Then click the big List Services button and check if the following services are enabled for you:

You need:

  • LXPLUS and Linux
  • AFS Workspaces
  • EOS/CERNBox

In case some of them are missing, just click on the service to subscribe. For Linux, you may be requested to provide a "group" and a "reason" for requesting the subscription.

  • Group: z2 (it corresponds to ALICE)
  • Reason: just type something like "new ALICE member", it's enough It will take at least two full working hours before you will be able to use the services
