For Experts

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

Under normal circumstances the online JAPAN instance is handled by the Analysis Minder GUI launched with CODA


Otherwise: 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
cd ../prompt.sh
./prompt.sh <run number>

Macro for Panguin

Experts can open a custom panguin session on completed runs. Instructions are listed in the "Expert" section on the Panguin page.
