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

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-
