Data Analysis with CMS

Finding Data

The easiest place to start is the cms workbook page on finding data here

The second option is by brute force looking through directory on eos (disk storage).

  • eos can be entered into a terminal on an lxplus machine and an interactive session will start. Commands such as ls and cd can be used to navigate directories. There is a directory called data that has most of the relevant global runs. Enter quit to get out of the session.
  • Another way is to use eos like this:
      $ eos ls eos/cms/store/data 

These file locations such as eos/cms/store/data/Run2015C/Cosmics/RAW/v1/000/253/982/00000/AAF77D5F-FF3F-E511-83B4-02163E0143BA.root are then entered into python files to be used by cmssw. More on this below.
