musrSim strawman setup

The following is a strawman setup of a two-layer MuPix-XY based detector for potential muSR applications. It is based on the mu3e software. 

Basic setup on merlin-l-001

Log in to merlin-l-001 with your username USER and install a mu3e developer environment (using ursl's forked bitbucket repo). The following is based on tcsh, you'll have to translate for bash or other versions. 

mkdir /data/user/$USER cd /data/user/$USER git clone git@bitbucket.org:ursl/mu3e mu3e-musrSim cd mu3e-musrSim git checkout ursl-musrsim source setup.csh git submodule update --init --recursive mkdir _build cd _build cmake .. make -j20

The initial part of the above procedure needs to be done once. Note that the sourcing of setup.csh will induce dependencies on langenegger's  (!) privately compiled GEANT version (the official mu3e software on merlin is not yet in that state because of the Qt dependency). It also changes your settings (in case they exist) for gcc, boost, git, cmake, Qt, ROOT, and eigen.

How to run

Running the GEANT4 geometry display

cd /data/user/$USER/mu3e-musrSim source setup.csh cd run mkdir data #or link to somewhere ../_build/mu3eVis

Running mu3eSim to show the GEANT trajectories

cd /data/user/$USER/mu3e-musrSim source setup.csh cd run ../_build/mu3eSim --gui
