Receivers/GEBMerge/GEBsort

To take data with the DGS DAQ, you must start a gtReceiver4 for each of the IOC that are collecting data. This is usually done from a scripts which starts all the necessary receivers necessary and controls the run number.

To get the gtReceiver4 do the following

• cd to where you want to compile the gtReceiver4

• wget http://www.phy.anl.gov/gretina/gtreceiver/tar.tgz

• tar -zxvf tar.tgz

• make clean

• make

That should generate the gtReceiver4 program. Here is an example how to run the program:

 gtReceiver4 ioc1 data_run_001.gtd 2000000000

Here we are asking gtReceiver4 to acquire data from ioc1 and put the data in the file data_run_001.gtd. That will not actually be one file as gtReceiver4 splits the data stream into a file for each of the digitizers the IOC serves. That makes it easier to merge and time order the DGS data later.
