Asked by abulikim2011

Hi. I just recently set up MadGraph5 on my ubuntu 14.04. I'm having this issue where all of the processes I've generated (such as p p > e+ e-) results ,ultimitly i want to run ExRootAnaysis ,events.lhe file convert events.root but it is not what is problem here?
Command "install ExRootAnalysis " interrupted in sub-command:
"install ExRootAnalysis" with error:
InvalidCmd : The environment variable ROOTSYS is not configured.
 You can set it by adding the following lines in your .bashrc [.bash_profile for mac]:
 export ROOTSYS=/usr
 export PATH=$PATH:$ROOTSYS/bin
 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib
 export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$ROOTSYS/lib
 This will take effect only in a NEW terminal

Hi,

Did you read/check the error message?
It explains the problem and how to solve it.
of course the line
> export ROOTSYS=/usr

might be different on your computer

Cheers,

Olivier
