General Instructions
The expert shifter must ensure that the online japan analysis is running and monitor panguin plots. In addition, they must execute offline analysis as instructed below.
Online JAPAN
To run an online instance of the JAPAN decoder execute
gojapan ./build/qwparity --config prex.conf --add-config online_apar.conf
This will automatically grab the current CODA run (it attaches to the 64 bit ET system and analyzes data on the fly) Looking at live plots can be done with PANGUIN in live mode as well, as long as your PANGUIN macro has the line
watchfile
included in it. A live PANGUIN session will update the plots on a few second cycle, but it can take some time to loop over all of the data. It is possible to trim down the ROOT file output size, which is especially useful in these circumstances. See here for more information.
Offline JAPAN
First login to apar@aonl1.jlab.org
. After the end of each run execute:
gojapan ./build/qwparity -r <run number> -c prex.conf
If auto-prompt is not running, then execute (with apar credentials)
cd ~/PREX/prompt ./auto_prompt.sh <run number> <0 or 1>
Use 0 option if you don't want to re-analyze existing runs, and 1 if you want to re-analyze existing runs.
