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
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
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
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
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-
