// These files for students analysis raw data
// There are files for root 5 or root 6 installed, along with instructions for how to convert from root 5 to root 6.
// Get the dependencies listed here: https://root.cern/install/dependencies
// (One of the downloads listed in the optinal dependencies didn't work for me)
// Next, follow https://root.cern/install/build_from_source/
// I started with git clone --branch v5-34-38 https://github.com/root-project/root.git root_src for root 5.
// This downloads it to a folder called root_src
// If you get error 2: This does not look like a tar archive, do: sudo apt install curl
// For root 6, you can install one of the pre-built binaries, or build it yourself using the instructions in the above links.
// To add ROOT to your environment variables (allows you to open it by just typing root), you need to follow these instructions:
// https://root.cern.ch/root/htmldoc/guides/users-guide/GettingStarted.html
// These will only work for the session you're in. To set them permanently, add them to your .bashrc file, a hidden file in your home directory. The ones I added for Ubuntu 20 were:
export ROOTSYS=$HOME/root
export PATH=$PATH:$ROOTSYS/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib
export PROJECT=$HOME/Documents/mu2e/ExampleRootForStudents // use your directory path
//
// Next, go into the main directory of your ForStudents files, open terminal, type make clean, then make. This compiles a bunch of necessary files for you.
//
// You'll need to untar the data .root file.
// Example untar file
$ tar xvjf file.tbz
// x = extract
// v = verbose, verbosely list files processed
// j = use bzip2
// f = file, take file input
//
// For us
$ tar xvjf data/1000evn.tbz
// Example analysis raw data
$ cd macros
/macros$ root -l
root[0] .L testShowProf_rawevent.cxx
root[1] testShowProf_rawevent("path/to/rootfile",100) //100 is the number of events
// as of initial commit, the path to the rootfile from the macros folder is "../data/1000evn_v3.root"
// with root6 in macOS
$ cd macros
