setenv LD_LIBRARY_PATH /usr/lib:/usr/local/lib:/usr/local/gcc-alt-3.2.3/lib
endif
# Switch to the old version of root, because monitoring is crashing with the latest one
setenv ROOTSYS /afs/cern.ch/sw/root/`cat ~/.rootversion | grep -v \#`/rh73_gcc32/root
setenv PATH ${PATH}:${ROOTSYS}/bin
setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${ROOTSYS}/lib
   2. add to ~/.cshrc and ~/.tcshrc:
      source $HOME/atlas_software/scripts/.ctbenv_csh
   3. add to ~/.zshrc:
      if [ ! "$LD_LIBRARY_PATH" ]; then
export LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:/usr/local/gcc-alt-3.2.3/lib

export PATH=${PATH}:${ROOTSYS}/bin
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${ROOTSYS}/lib
. $HOME/atlas_software/scripts/.ctbenv_zsh
   4. create a .rootversion file:
      cat >.rootversion
      and type:
      v3.10.02
      press CTRL+D at the end
4. if you allready have a atlas_software directory enter it:
   cd atlas_software
   or create and enter it:
   mkdir ~/atlas_software
cd ~/atlas_software
5. copy the scripts directory of user ddobos to your home directory:
   cp -r ~ddobos/atlas_software/scripts ~/atlas_software
   enter the scripts directory:
   cd ~/atlas_software/scripts
6. create the other necessary directories:
   mkdir ~/atlas_software/misc
mkdir ~/atlas_software/LSF
mkdir ~/atlas_software/scratch0
mkdir ~/atlas_software/scratch0/log
rfmkdir $CASTOR_HOME/ctb_output
rfmkdir $CASTOR_HOME/ctb_output/ntuple
rfmkdir $CASTOR_HOME/ctb_output/listing
rfmkdir $CASTOR_HOME/ctb_output/transfered
7. check if you have copied the both environmental scripts:
   ls ~/atlas_software/scripts/.ctben*
8. update the castor path saved in ~/atlas_software/scripts/.ctben_csh and ~/atlas_software/scripts/.ctben_zsh:
   sed s/'user\/d\/ddobos'/'user\/<youruserinitial>\/<yourusername>'/ >.ctbenv_csh.new && mv .ctbenv_csh.new .ctbenv_csh
sed s/'user\/d\/ddobos'/'user\/<youruserinitial>\/<yourusername>'/ >.ctbenv_zsh.new && mv .ctbenv_zsh.new .ctbenv_zsh

Test RecExTB:

1. enter your scripts directory:
   cd ~/atlas_software/scripts
2. execute the getruns script:
   getruns
3. execute the submit script:
   submit <numberofruns> <release> <runnumber> (e.g. <numberofruns>=1 <release>=9.0.0 <runnumber>=2102722)
4. check from time to time (if everything is fine the LSF job should take at least an hour) with:
   bjobs
   if the LSF job finished
5. if the job finished, copy the root file to your scratch0 directory:
   rfcp $CASTOR_HOME/ctb_output/ntuple/ntuple_run<runnumber>.root ~/atlas_software/scratch0
6. enter the RecEcTB root directory:
   cd ~ddobos/atlas_software/RecExTB/9.0.0/Reconstruction/RecExample/RecExTB/RecExTB-00-00-55/root
