Meeting notes

Data and DAQ are located and working in the opsmdaq0 machine

CODA directory structure

all directories are under /opt/idaq. All files contained here MUST be used only by EXPERTS!

• crl files or configuration files are: /opt/idaq/crl/
• scripts like epics and logentry scripts are in: /opt/coda/scripts

IDAQ user directories

There is a general directory used by idaq the user:

 /work/idaq

These are the official version files! USE THEM BUT DO NOT MODIFY THEM! If you want to do it, copy them in your personal directory. Under this general directory you will find the Analysis subdirectory where there are all these subdirectories:

   CVS  decoder  macroes  pedestalfiles  rootfiles  txtfiles

• decoder software for the ntuple generation (from raw data to root file). When you run it you will generate 2 files, one the root file and a txt file with a summary of the data taking conditions. They will be located in the following directories:
• rootfiles directory where all the .root files are placed. Each detector has its own subdirectory (annihilation, mott, peppo)
• txtfiles directory used to store the summary of the data taking conditions of the run
• macroes directory with the macroes for the run analysis
• pedestalfiles directory with all the fit values of the pedestal fit used in the ananlysis
• CVS directory with the previous versions of the software used. There are 2 subdirectories: decoder and macroes

There are also short cuts for the idaq user, use them, it is easy! => put a $ before the short cut name (EX. cd $ANALYSISDIR will bring you directly in the /work/idaq/analysis directory)

• IDAQDIR /work/idaq
• ANALYSISDIR /work/idaq/Analysis
• DECODERDIR /work/idaq/Analysis/decoder
• MACROESDIR /work/idaq/Analysis/macroes
• ROOTFILESDIR /work/idaq/Analysis/rootfiles
• TXTFILESDIR /work/idaq/Analysis/txtfiles
• PEDESTALFILESDIR /work/idaq/Analysis/pedestalfiles
• CVSDIR /work/idaq/Analysis/CVS

Webserver files and group disk

On the cue
