This page contains instructions for setting up and using a tool to parse text files and create ntuples containing the information in them.

Set up the environment

The command


runs the program on a text file.

The code is executed via the command:

runFillFlatFromAscii teststeerFillFlatFromAscii.txt  testFlatFillATLASl4vec.txt  testFlatFillATLAS.root

The first argument is the steering file, the second is the text file you make and the third is the output root file.

The steering file should be pointed at the evinfo, global and variable tree to ntp definitions.

For initial setup:

source ~cdfsoft/cdf2.shrc

setup cdfsoft2 6.1.6.m

cd /data/cdf04/stdenis/hww_1fb/hwwcdf6.1.6.mv4_81/

srt_setup -a

cd -

Test environment -- CDF Version

Copy the following files into a test area:






Edit teststeerFillFlatFromAscii.txt so the three files have no directory spec:

GeneralParameter string 1 TreeSpecEv=TreeSpecEv.txt

GeneralParameter string 1 TreeSpecGlobal=TreeSpecGlobal.txt

GeneralParameter string 1 TreeToNTPMapFile=VariableTreeToNTP.txt

Now do:

setup neurobayes_expert

setup root v5_26_00 -q GCC_3_4_6 -f Linux+2.6

Now you can run the tool via the command

runFillFlatFromAscii teststeerFillFlatFromAscii.txt  testFlatFillATLASl4vec.txt  testFlatFillATLAS.root
