Ntuple Production At TTU

First login to lxplus and setup you dream GRID account then login to antaeus

gsissh hugin.hpcc.ttu.edu -p 49922

move to the directory where the myDaq2Ntu program resides

cd /lustre/hep/osg/dream/Ntuple_gen/DreamDaq/decode

Note date is generally sorted by year, for example /lustre/hep/osg/dream/2014/storage/ so check the directory needed for the current or applicable year.

source the setup scripts and set your input and output folders

source setup4myDaq2Ntu_running.sh

source setuproot.sh 5.30.01

export DATADIR=/home/GRIDUSERS/dreamdaq/dream/working_bak

export NTUPLEDIR=/home/GRIDUSERS/dreamdaq/dream/Ntuple_gen/ntuples/test

you can use the gen_ntuple.py script, e.g.

gen_ntuple.py 5399 create the ntuple for run 5399

gen_ntuple.py 5399 - 5500 create ntuples for all runs between 5399 and 5500

gen_ntuple.py 5399 5400 5899 create ntuples for all the listed runs

Note for runs between 4700 and 5284

Runs between 4909 and 5055 were taken with a faulty DRS setting and are useless (as far as the DRS is concerned).

Runs taken in July before the 5284 suffer from a DRS misalignment problem. The issued has been solved offline and the corresponding files can be found in /home/GRIDUSERS/dreamdaq/working_bak/corrected. To use this folder you can, for instance, do the following

export DATADIR=/home/GRIDUSERS/dreamdaq/dream/working_bak/corrected

Compiling myDaq2Ntu

If you have made any modifications to myDaq2Ntu.c you'll need to recompile it. First setup the include directories

source setup4myDaq2Ntu_running.sh

then compile it with

make

Setting up input and output directories

How to use setup_input_output.sh script (This script helps you set the input and output directories)

source setup_input_out.sh : This script will set the default paths for the input and output directories.

source setup_input_out.sh /input/path /output/path : If you specify two arguments, the first argument will be the input path and the second will be the output path.
