===CODAreader===
 +
 +
A temporary system of converting CODA data files to ROOT files and analyzing them.
 +
 +
The programs are located in DAQ's subdirectory
 +
 +
/home/daq/CODA/CODAreader/ROOT_V5.30/R1DC
 +
 +
 +
the program
 +
 +
evio2nt
 +
 +
is used to convert the raw CODA data file into a ROOT tree.  Here is an example of the commands used
 +
 +
first setup the environmental variables (you only need to do this once at the beginning)
 +
 +
source ~/CODA/2.6.2/setup
 +
 +
source ~/src/root/root-5.34.00/bin/thisroot.csh
 +
 +
now execute the command
 +
 +
./evio2nt -f/home/daq/r3804.dat
 +
 +
the CODA data file located at /home/daq/r3804.dat will be used to generate the file
 +
 +
/home/daq/r3804
 +
 +
root will recognize the root file if you add the extension .root
 +
 +
mv /home/daq/r3804 /home/daq/r3804.root
 +
 +
You can now use root to look at the TDC hits with the commands
 +
 +
root -l /home/daq/r3804.root
 +
 +
R1DC->Draw("(evt.TDC1190[1])/10","abs(evt.TDC1190[121]-evt.TDC1190[123])<100");
 +
 +
the TDC time for channel 1 will be plotted in nanoseconds and a timing cut will require the 2 scintillator hits to be within 10 ns of eachother.
 +
 +
You can look at individual TDC hits using this ROOT file
 +
 +
R1DC->Draw("(evt.TDC1190[29])/10");
 +
R1DC->Draw("(evt.TDC1190[31])/10");
 +
R1DC->Draw("(evt.TDC1190[31]-evt.TDC1190[29])/10");
 +
 +
 +
===R1DC===
 +
 +
A ROOT script is available to look at the hits graphically
 +
 +
you need to edit the file
 +
 +
R1DC.h
 +
 +
and set the root filename you wish to visualize.  Look for lines in the code which resemble this
 +
 +
    TFile *f = (TFile*)gROOT->GetListOfFiles()->FindObject("/home/daq/r3804.root");
 +
      if (!f || !f->IsOpen()) {
 +
        f = new TFile("~/r3804.root");
 +
 
 +
change run number as needed.
 +
 +
after that you can begin visualization using the commands below
 +
 +
root -l
 +
 +
.L R1DC.C
 +
 +
R1DC t;
 +
 +
t.loop();

Download EVIO

EVIO 2.2

evio-2.2

cd CODA/evio/evio-2.2/

1.) set the environmental variable to tell the software where CODA is 

setenv CODA_HOME /home/daq/CODA/evio/evio-2.2

setenv LD_LIBRARY_PATH $CODA_HOME/Linux-i686/lib/


2.) While in the directory evio-2.2 run scons to compile everything 

scons

3.)

Linux-i686/bin/evio2xml ~/test.dat | less


4.) If you type 

scons install

the programs will be moved to the CODA_HOME subdirectory under Linux-

CODAreader

A temporary system of converting CODA data files to ROOT files and analyzing them.

The programs are located in DAQ's subdirectory 

/home/daq/CODA/CODAreader/ROOT_V5.30/R1DC


the program 

evio2nt

is used to convert the raw CODA data file into a ROOT tree. Here is an example of the commands used

first setup the environmental variables (you only need to do this once at the beginning) 

source ~/CODA/2.6.2/setup

source ~/src/root/root-5.34.00/bin/thisroot.csh

now execute the command 

./evio2nt -f/home/daq/r3804.dat

the CODA data file located at /home/daq/r3804.dat will be used to generate the file 

/home/daq/r3804

root will recognize the root file if you add the extension .root 

mv /home/daq/r3804 /home/daq/r3804.root

You can now use root to look at the TDC hits with the commands 

root -l /home/daq/r3804.root

R1DC->Draw("(evt.TDC1190[1])/10","abs(evt.TDC1190[121]-evt.TDC1190[123])<100");

the TDC time for channel 1 will be plotted in nanoseconds and a timing cut will require the 2 scintillator hits to be within 10 ns of eachother.

You can look at individual TDC hits using this ROOT file 

R1DC->Draw("(evt.TDC1190[29])/10");
R1DC->Draw("(evt.TDC1190[31])/10");
R1DC->Draw("(evt.TDC1190[31]-evt.TDC1190[29])/10");


R1DC

A ROOT script is available to look at the hits graphically

you need to edit the file 

R1DC.h

and set the root filename you wish to visualize. Look for lines in the code which resemble this 

    TFile *f = (TFile*)gROOT->GetListOfFiles()->FindObject("/home/daq/r3804.root");
     if (!f || !f->IsOpen()) {
        f = new TFile("~/r3804.root");

change run number as needed.

after that you can begin visualization using the commands below 

root -l

.L R1DC.C

R1DC t;

t.loop();

EVIO 4.0

Prereqs

sudo yum install {expat,libz}-devel

on DAQ2 i had 4.0 installed in

~/CODA/evio/evio-4.0

I set the environmental variable

export CODA_HOME ~/CODA/2.6.2


I ran scons to compile evio-4.0 in the subdirectory


libraries were installed in the subdirectory

/home/daq/CODA/evio/evio-4.0/src/2.6.2/Linux-i686/lib/

svn

On 4/12/12 EVIO was being distributed using SVN and only on a jlabX machine onsite

If you login to a jlab machine you can see the contents of the repository using the command

svn ls svn://phecda.jlab.org/daqfs/source/svnroot/

Check Out

svn co svn://phecda.jlab.org/daqfs/source/svnroot/evio-4.0

Compile evio library on CODA machine

evio-2.2

1.) set the environmental variable to tell the software where CODA is 

setenv CODA_HOME /usr/local/coda/2.5

setenv LD_LIBRARY_PATH $CODA_HOME/Linux6-86

2.) While in the directory evio-2.0 run scons to compile everything 

scons

3.) If you type 

scons install

the programs will be moved to the CODA_HOME subdirectory under Linux-
