RAT for Ricochet

1. Install Prerequisites - Before downloading RAT, make sure you install the software packages in this order.

2. Download RAT - Run git clone in your working directory. This puts RAT in a new directory called rat.

3. Set up ROOT and GEANT4

• By sourcing their respective environment scripts: $ROOTSYS/bin/thisroot.sh and $G4INSTALL/geant4.10.01.p02-build/InstallTreeFiles/geant4.sh
  

4. Run the following commands (in the rat directory) to build RAT

# Run configure script
./configure

# Setup Environment
source env.sh

# Compile
scons

SUMMARY OF STEPS FOR EVERY LOGIN SESSION

cd /afs/hep.wisc.edu/ddm/ratcage
source env.sh

Note: The sourcing of env.sh only has to be done once per login session.

Example testCfneutrons.mac

# Set environment variables with
source /afs/hep.wisc.edu/ddm/ratcage/env.sh

# The neutron detector at the MIT reactor geometry is at
cd /afs/hep.wisc.edu/ddm/ratcage/rat/data/Ricochet/NCD_MITR.geo
  
# and other info is in the /data directory (MATERIALS, SPECTRUM, ELEMENTS)
# Run the macro example by typing
rat testCfneutrons.mac

# You will see an output root file and it is useful to make a ROOT program to make histograms from it
# To see the outcome plots, you need to execute makeNeutronPlotsNCD.C
# Follow these commands
root -l 
root[0] .L makeNeutronPlotsNCD.C+
root[1] makeNeutronPlotsNCD("testNeutronCf.root","histTestneutronCfNew.root")

You can learn a lot about a ROOT file with the TBrowser() but it's all listed in https://deapclean.org/rat/trac/wiki/UserGuide/DataStructure/MC

The following is a work in progress.

1. Research Notes

1. 1. Installation

Sourcing environment for ROOT and RicochetSim

```bash source /afs/hep.wisc.edu/ddm/Ricochet/env.sh; source /cvmfs/sft.cern.ch/lcg/releases/gcc/7.3.0-cb1ee/x86_64-centos7/setup.sh ```

make a `build` directory in `/SimuAnalysis/`

from `/SimuAnalysis/build` directory

• • CMake Step**

Run the following

```bash cmake -DCMAKE_INSTALL_PREFIX=/afs/hep.wisc.edu/users/decheine/myapps -DCMAKE_CXX_FLAGS=-isystem\ /afs/hep.wisc.edu/ddm/Ricochet/CLHEP_dir/build .. ```

or whatever install directory you'd want, the default is /usr/local.

1. 1. 1. Notes on Installation

1. 1. 1. 1. Misc. Util commands

List the sizes and sort directories

> du -h --max-depth=1 | sort -hr

```bash source /afs/hep.wisc.edu/ddm/Ricochet/env.sh; source /cvmfs/sft.cern.ch/lcg/releases/gcc/7.3.0-cb1ee/x86_64-centos7/setup.sh ```

1. 1. 1. 1. Workaround Commands

These three are run after cmake is run. With new branch, these might not be needed

```bash find CMakeFiles/*.dir/link.txt -type f -exec grep -l "/builds/deployment/deploy-externals/build/lib" {} \; | xargs sed -i 's/\/builds\/deployment\/deploy\-externals\/build\/lib/\/cvmfs\/lz.opensciencegrid.org\/external\/ROOT\/6.16.00\/x86_64-centos7-gcc7-opt\/lib/g'; find CMakeFiles/*.dir/build.make -type f -exec grep -l "/builds/deployment/deploy-externals/build/lib" {} \; | xargs sed -i 's/\/builds\/deployment\/deploy\-externals\/build\/lib/\/cvmfs\/lz.opensciencegrid.org\/external\/ROOT\/6.16.00\/x86_64-centos7-gcc7-opt\/lib/g'; find CMakeFiles/*.dir/flags.make -type f -exec grep -l "++1z" {} \; | xargs sed -i 's/++1z/++17/g'; find CMakeFiles/*.dir/flags.make -type f -exec grep -l "++14" {} \; | xargs sed -i 's/++14/++17/g' ```

and for RicochetSim

```bash find */CMakeFiles/*.dir/link.txt -type f -exec grep -l "/builds/deployment/deploy-externals/build/lib" {} \; | xargs sed -i 's/\/builds\/deployment\/deploy\-externals\/build\/lib/\/cvmfs\/lz.opensciencegrid.org\/external\/ROOT\/6.16.00\/x86_64-centos7-gcc7-opt\/lib/g'; find */CMakeFiles/*.dir/build.make -type f -exec grep -l "/builds/deployment/deploy-externals/build/lib" {} \; | xargs sed -i 's/\/builds\/deployment\/deploy\-externals\/build\/lib/\/cvmfs\/lz.opensciencegrid.org\/external\/ROOT\/6.16.00\/x86_64-centos7-gcc7-opt\/lib/g'; find CMakeFiles/*.dir/flags.make -type f -exec grep -l "++1z" {} \; | xargs sed -i 's/++1z/++17/g'; find CMakeFiles/*.dir/flags.make -type f -exec grep -l "++14" {} \; | xargs sed -i 's/++14/++17/g' ```

• • CLHEP Fix**

add `-DCMAKE_CXX_FLAGS=-isystem\ /afs/hep.wisc.edu/ddm/Ricochet/CLHEP_dir/build` flag to the cmake call

In SimuEventDisplay.dir/build.make, line 82 has

``` d SimuEventDisplay: /cvmfs/sft.cern.ch/lcg/releases/gcc/7.3.0-cb1ee/x86_64-centos7/include/TEveManager.h ```

Maybe this should be

• • WORKING** Added "ROOT::Eve" to both include statements

Two header files that are misbehaving are Counter.h and SimuHisto.h

GOT IT. NEED TO PUT `${PROJECT_NAME}$` at the end of the second 'target_link_libraries(...)'

rule to replace /builds/deployment/deploy-externals/build/lib/ with /cvmfs/lz.opensciencegrid.org/external/ROOT/6.16.00/x86_64-centos7-gcc7-opt/

1. 1. 1. 1. Directories

Cmake binary

/afs/hep.wisc.edu/ddm/Ricochet/cmake-3.12.1/bin

CXX Compiler

/cvmfs/cms.cern.ch/slc6_amd64_gcc530/external/gcc/5.3.0/bin/c++ Using

```bash cmake -DCMAKE_CXX_FLAGS=-isystem\ /afs/hep.wisc.edu/ddm/Ricochet/CLHEP_dir/build -DCMAKE_CXX_COMPILER=/cvmfs/cms.cern.ch/slc6_amd64_gcc530/external/gcc/5.3.0/bin/c++ .. ```

Fixes the "string_view" problem and makes it compile with c++ 17. or not i guess

• • String_view problem** just delete build folder, and make sure to include

```cmake set(CMAKE_CXX_STANDARD 17) set(CMAKE_CXX_STANDARD_REQUIRED ON) ```

do cmake again

ROOT

/cvmfs/lz.opensciencegrid.org/external/ROOT/6.16.00/x86_64-centos7-gcc7-opt/

This needs to be in the include directory: /cvmfs/lz.opensciencegrid.org/external/ROOT/6.16.00/x86_64-centos7-gcc7-opt/include/

1. 1. 1. 1. Procedures

Listed here are some miscellaneous commands and tricks that may be useful.

In root, get the include path with `root[] .I`

To search a directory `path `in linux for files that contain text `"string"`,

``` bash grep -rl "string" /path ```

List the ROOT LIBRARIES

```bash root-config --glibs ```
