- If you are not already familiar with ROOT there are many good tutorials on the web. I recommend this one. You can download ROOT, read the users manual, find support forums and more all at root.cern.ch.
- On the UT ATLAS cluster, log off and log in again. The ATLAS setup scripts should now have run as you logged in and you should be able to setup ROOT with
localSetupROOT. - Now you can start root with
root -l. - At this point you should be able to follow the tutorial mentioned above. It comes with some introductory slides that you can check out. There are some files you'll need that you can grab with
wget -r --no-parent --reject "index.html*" http://www.nevis.columbia.edu/~seligman/root-class/files.
Getting Started on the Grid:
- Request a grid certificat and membership in the ATLAS and USATLAS VO: https://www.racf.bnl.gov/docs/howto/grid/gridcertfaq
- Export the certificate from your browser (or keychain) and save as .p12 file. Copy the file over to the cluster.
- Install the certificate https://www.racf.bnl.gov/docs/howto/grid/installcert
- Check that it works using
voms-proxy-init -voms atlas:/atlas/usatlas
Analysis Software
The next steps will involve specific analysis software, and there are several possibilities (most require access to ATLAS webpages).
