h1. DAQ
DAQ is running on simonadaq computer in coda account in the vnc session number 1.
To open VNC, either start VNC from a computer at the counting house through ssh or make a ssh tunnel if you are offsite
Example :
ssh -L5901:locahost:34567 username@hallgw.jlab.org ( use a port number not in used on hallgw )
after from hallgw
ssh -L34567:localhost:5901 cdaq@simonadaq
then open a vnc locally on your computer : vncviewer -shared localhost:1 ( ask Junqi or Sylvester for the vnc password )
To start CODA from scratch, login as coda
type startcoda
that will open the CODA windows
If the ROC is not started alread, ssh root@hallcsc-1 and type ./startroc1
in Run Control GUI, go to platform and connect.
Then choose the FADC configuration and just start a run.
To change the FADC parameters,
ssh to hallcsc-1 as root
go to /root/linuxvme/fadc/rol
and edit fadc_list.c
once done compile with :
make fadc_list.so
and redownload in CODA to take the changes into account
I saw from time to time error in FADC ROC window about scanmask, usually stopping the run and redownloading fixes the issue.
h1. FADC data analysis
on cdaq account
go to /home/cdaq/tlgc/FADC_decode
and run FADCcom program
you need to copy the CODA file from simonadaq to /net/cdaq/cdaql1data/cdaq/tlgc/data ( from simonadaq : scp fadc_runnumber.dat cdaq@cdaql2:tlgc/data/ )
if you open the rootfile you will see the different directories corresponding to the channels decoded.
