GettingStarted Using ROOT

Getting Started Using ROOT

• Get access to JLab computers and join the XEM group. Run the environment setup shell/cshell script:

source /group/c-xem2/software/setup.csh

• Look at the CERN ROOT Users Guide (2018)

[ROOT User's Guide] Pay close attention to Histograms, TTree, A Little C++

• Look at the CERN ROOT documentation for specific class objects under our specific ROOT version (currently 6.22/06)

[https://root.cern.ch/doc/v622/classTH1.html] Notice the v622 refers to version 6.22 (our current version of ROOT)

• Get Hall C analyzer-specific information

[| Hall C Analysis Meeting] Not all of this information is applicable to us. We do not use a virtual machine unfortunately, just the usual JLab environment. Make sure you check out the videos too, they are more explanatory than old powerpoints.

• Check out the getting started section of the wiki:
