bin/runTreeReaders -r bmmReader -c chains/100407.data -C cuts/bmmReader.default.cuts (for prompt reco data)

You can redirect the output rootfile with -D ~/somewhere/.

If you are using a bash, you'll need to translate the 'setenv LD_LIBRART_PATH ...' command appropriately.

runTreeReaders.cc is a wrapper executable that instantiates tree classes to be run and provides some command line parsing and other setup utilities.

The class bmmReader is just an example for an analysis class. It inherits from treeReader01 (some of the stuff which needs virtually no editing is in treeReader01.icc).

When you produce a class (presumably derived from treeReader01 or even from bmmReader), and if it is needed for the final analysis (validation, normalization, whatever), please add it to runTreeReaders.cc.

If you want to run in batch:

cd chains/batch1
run -c ../../tree.csh  -t ../../../../../grid-100427.tar.gz  
-m batch -x 'bin/runTreeReaders -n 900 -r muCharmReader -C cuts/muCharm.default.cuts' 
-r 'STORAGE1 srm://t3se01.psi.ch:8443/srm/managerv2\?SFN=/pnfs/psi.ch/cms/trivcat/store/user/ursl/root/trees/batch1' chain*

Note: The output filename is determined by the chain name. If you want to submit batches with different cut files, you have two options:

• store the output into different SE locations
• name the chain files according to the different cut scenarios
