An older version of the library is available to ATLAS users and stored in the ATLAS central CVS repository at atlas/groups/SUSY/mT2/ in the central ATLAS CVS repository.You should be able to check out the code with something like this:
mkdir -p ~/some/working/directory cd ~/some/working/directory kinitThen to actually check out the mT2 package you need to do one of the following two lines. (Try one and if it doesn't work try the other. Which one you need to use depends on which version of kerberos you have. At CERN on lxplus you seem to need to use the "gserver" version, whereas in Cambridge I have to use the "kserver" option): EITHER
cvs -d :gserver:firstname.lastname@example.org:/atlascvs co -d mT2 groups/SUSY/mT2OR
cvs -d :kserver:email@example.com:/atlascvs co -d mT2 groups/SUSY/mT2
The latest stable tag is
Having done the above, you should then see that you have created a directory "mT2" containing some other subdirectories:
[localhost] /usera/lester/some/working/directory > ls mT2 [localhost] /usera/lester/some/working/directory > ls mT2/ bin CVS examples Makefile.include README ChangeLog docs Makefile Mt2 srcEnter the main directory:
cd mT2Before you can build, if you are not running on LXPLUS you will need to make sure that the file
Makefile.includeis customised to reflect your own location, as this file specifies whether the external package MINUIT2 (on which the library depends) will be found. MINUIT2 libraries come with ROOT (or SEAL if you want them without ROOT) for example at
/afs/cern.ch/atlas/software/releases/sw/lcg/external/root/5.13.04b/slc3_ia32_gcc323/root/lib/libMinuit2.soor for those of you without afs access there is a ROOT-free version of Minuit that can be downloaded from the Minuit2 homepage. Back to the installation of the Oxbridge Stransverse Mass Library: The only lines of the file
Makefile.includewhich you might need to edit are the following: (the default values of
slc3_ia32_gcc323work on LXPLUS as of 8th June 2007 ).
# For Minuit2: #For lxplus.cern.ch: # Choose your ROOT vesion: #ROOTHOME := /afs/cern.ch/sw/lcg/external/root/5.15.08/osx104_ppc_gcc401/root #ROOTHOME := /afs/cern.ch/sw/lcg/external/root/5.15.08/slc3_ia32_gcc323/root #ROOTHOME := /afs/cern.ch/sw/lcg/external/root/5.15.08/slc3_ia32_gcc323_dbg/root #ROOTHOME := /afs/cern.ch/sw/lcg/external/root/5.15.08/slc4_ia32_gcc34/root #ROOTHOME := /afs/cern.ch/sw/lcg/external/root/5.15.08/slc4_ia32_gcc34_dbg/root ROOTHOME := /afs/cern.ch/sw/lcg/external/root/5.15.08/slc4_amd64_gcc34/root #ROOTHOME := /afs/cern.ch/sw/lcg/external/root/5.15.08/slc4_amd64_gcc34_dbg/root #ROOTHOME := /afs/cern.ch/sw/lcg/external/root/5.15.08/win32_vc71_dbg/root
Makefile.include is safely tailored to your system, you should be able to go to the top-directory type:

Date: Wed, 13 Jan 2010 16:53:08 +0000 From: Christopher Cowdenfile:///afs/cern.ch/atlas/offline/external/mT2 for the mT2 package hosted in Cambridge svn.
To: Dustin Urbaniec , Francesco Spano' , Christopher Lester Subject: StransverseMassUtils update Hi Everyone, This is just a quick update on the status of Atlas External mT2 development. mT2 has been build for various platforms/architectures/compiler versions/etc. in the allotted afs space. AFS External space: /afs/cern.ch/atlas/offline/external/mT2 The glue package AtlasmT2, which sets up the proper environment for the Atlas software, has been added to the Atlas svn repository under External/AtlasmT2. The latest tag of this package is AtlasmT2-00-00-01. It should be going into the nightly builds tonight or tomorrow. Since this isn't yet in a working release, it must be checked out using svn co $SVNROOT/External/AtlasmT2/tags/AtlasmT2-00-00-01 External/AtlasmT2 Then the usual "cmt config..." as for any other package. The StransverseMassUtils package is still in the svn repository in Cambridge, but has been updated to cope with the afs space and AtlasmT2 package. The StransverseMassUtils package is ready to go into the software, but we need to decide which project should it belong and where in svn it should belong. At the moment I've assumed it to be in PhysicsAnalysis/AnalysisCommon, but this could be changed quite easily. I think we should request the package be added asPhysicsAnalysis/AnalysisCommon/StransverseMassUtils as part of the AtlasReconstruction project. Regards, C
