installation of Delphes can't find root

Do you have ROOTSYS environment variable defined?

Cheers,

hi Olivier,

Thanks...From my .bashrc file:

export PATH=$ROOTSYS/bin:$PATH
export LD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATH
cd root
. bin/thisroot.sh
cd

and:

chipbrock@ubuntu:~$ echo $PATH
/home/chipbrock/root/bin:/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

Hi,

Then I have no idea.
Clearly the program fails to find root, I don't know why.
The easiest solution is to comment the line who makes the installation to crash:
file madgraph/madgraph_interface.py around line 676:
remove the lines:
            if not misc.which('root'):
                raise self.InvalidCmd(
'''In order to install ExRootAnalysis, you need to install Root on your computer first.
please follow information on http://root.cern.ch/drupal/content/downloading-root''')

Cheers,

Olivier

Wow. Didn't want to hear that! If I were to install Delphes independently, does the madgraph installation set up any soft links or environment variables? Does it go into a particular directory? In short - how might I independently install delphes 3 to make it an identical circumstance as when madgraph does it for me?

You probably don't remember me, but we met at Duke at Ashutosh's EW working group meeting. I'm moving myself into a linux environment in vmware and getting off the mac OS. Starting to worry about Apple's move to iOS everything and I suspect their being behind in their BSD support. I'll count on VMWare keeping up.

But this Root thing has me really confused!

thanks

Hi,

You are free to install Delphes independently, no problem on that.

No we don't

You need to do three things:
1) install Delphes on your system. (We use currently the following link: http://cp3.irmp.ucl.ac.be/downloads/Delphes-3-current.tar.gz)
2) modify the file input/mg5_configuration.txt and set the path to your Delphes installation.
3) overwrite the file Template/Cards/delphes_card_default.dat by a valid Delphes3 configuration cards (by default this file is still a Delphes2 file since we support both Delphes2 and Delphes3)

Sorry I didn't associate the name on the face, but sure I remember you.

> But this Root thing has me really confused!

Just that Delphes needs to have root installed in order to work.
For some reason, MG5 fails to detect root on your path (or consider it as not executable).
MG5 then stops wrongly the installation (I prefer to stop the installation such that the user knows that some external program are required.

Cheers,

Olivier

Hi Olivier,

    I had exactly the same symptom as Raymond, and it seems that this problem is indeed caused by the variable ROOTSYS. I installed my root following the instruction on http://www.csupomona.edu/~pbsiegel/phy499/rootinstall.html. According to this website, I added:

export PATH=$ROOTSYS/bin:$PATH
export LD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATH
cd root
. bin/thisroot.sh
cd

at the very end of the .bashrc file, but I cannot install Delphes in mg5. ( I was wondering if it is the position that cause this problem?)

Luckily, I tried to command "export ROOTSYS=$HOME/root" first in the terminal, then commanded "install Delphes" in mg5, and the installation problem seems to be fixed now.

Hi,

Thanks for the solution.
Indeed $ROOTSYS need to be define.

Cheers,

Olivier
