How to run Vetra on the online cluster

This page describes how to run Vetra on a computer in the LHCb Online System Environment and therefore it requires you to have a username on the online network. The page also describes how to configure your account on the online network to work with getpack , the script used to check out software from CVS. If you don't know how to get access to the online network, I suggest that you have a look on this page where you will find info on how to get an "online account" and more.
Line: 7 to 8
  When logged on to the online network (lbgw.cern.ch from a computer on the CERN network), the first step is to set up the Vetra environment properly. This is done with the command
Changed:

SetupProject Vetra [By default the latest version available. If you want another version you can specify it.]

which will configure your environment for the latest version of Vetra that's available. It includes the "source setup.sh" command that was necessary in older versions.

You will find the Vetra installation in /group/velo/sw/cmtuser/Vetra_vXrY/. The command Vetra.exe has been aliased to the correct executable. Remember that you are now working with a group installation so think twice before you start changing options files and recompiling. Always make backups!

In $VETRAROOT/options you will find plenty of options files to use. The file named VetraNZS.opts is a good starting point if you want to do simple NZS analysis (noise, pedestals, ...).
You can find an example on how to run a noise analysis here.
