Notes on how to run AMA taken from the tutorial: https://twiki.cern.ch/twiki/bin/view/AtlasProtected/AMATutorial

setting up AMA

For general setup see tutorial, once set up, do:

cd atlas/testarea/15.0.0/PhysicsAnalysis/AnalysisCommon/AMA/AMAAthena
source init.sh

data sample definition file

One can define local samples via

define_sample zmumu_AOD /afs/cern.ch/atlas/offline/external/FullChainTest/tier0-vol3/ama/tutorial/

which would put the contents of the directory in a file named samples/zmumu_AOD.def, use castor with a valid grid certificate via

define_castor_sample /castor/cern.ch/grid/atlas/tzero/prod2/perm/fdr08_run2/physics_Egamma/0052283/fdr08_run2.0052283.physics_Egamma.merge.AOD.o3_f8_m10/

or dq2 via

define_dq2_sample mc08.107663.AlpgenJimmyZmumuNp3_pt20.recon.AOD.e352_s462_r541_tid026388
or
define_dq2_sample mc08.107663.AlpgenJimmyZmumuNp3_pt20.recon.AOD.e352_s462_r541_tid026388 100

where the latter command would specify the number of collections per sample definition file.

Further examples can be found at https://twiki.cern.ch/twiki/bin/view/Main/FileStager

Note: define_dq2sample only looks at CERN-PROD_MCDISK by default. If the files are located at another site, specifiy it like this:

define_dq2_sample user.RichardHawkings.0108173.topmix_Egamma.AOD.v2 -1 DESY-ZN_PHYS-TOP

To find out where the samples are located, do

dq2-ls -r user.RichardHawkings.0108173.topmix_Egamma.AOD.v2
