| + | == Loading the Decomp File == | ||
| + | |||
| + | Once all the above files have been created, we can load them into the GRETINA DAQ. To do this, we must be logged into the **gretina** account preferably on the computer currently hosting the gretina daq (currently this is **a2.gam**) | ||
| + | |||
| + | On gretina: | ||
| + | |||
| + | <code> | ||
| + | cd ~/DecompParam | ||
| + | mkdir detmaps_yymmdd | ||
| + | </code> | ||
| + | |||
| + | where yymmdd in the above is replaced with the year, month and date respectively. After this directory is created copy all the above created files into the newly created directory. | ||
| + | |||
| + | Now we must copy/edit the setfile. The setfiles are located in **~gretina/DecompParam/** Copy the last setfile to the current date: | ||
| + | |||
| + | <code> | ||
| + | cp setFile.2017-02-09 setFile.YYYY-MM-DD | ||
| + | </code> | ||
| + | |||
| + | Now the newly created setfile must be edited. Assuming we keep the standard naming convention mentioned here; all one needs to do is a mass search and replace for the old date with the new date. Using 2017-02-09 as the old example and YYYY-MM-DD as the new example | ||
| + | |||
| + | <code> | ||
| + | 170209 -> YYMMDD | ||
| + | </code> | ||
| + | |||
| + | Once the new setfile is edited to point to the newly created Decomp files, we must tell the gretina daq to load use this new setfile. This is done by editing the file **~gretina/grdecomp.sh** In the file, the parameter FILECONF should be edited to point to the newly created setfile. This parameter is at the top of the file in the first uncommented line. The convention is to copy the line, comment out the old definition, and change the setfile name in the new line. | ||
| + | |||
| + | |||
| + | == Loading new Decomp Parameters == | ||
| + | |||
| + | Once all the above is done, we must tell the daq to load the new decomp values. This can be done either using the buttons, **GRETINA Stand Alone** of **GRETINA + S800**, or by running the script **~gretina/grdecomp.sh** directly. | ||
| + | |||
| + | After the above load - the daq should be started and left to run for a few minutes. If there is some mistake in the loading of the above files, this will cause the buffers for the bad channels to fill up and the daq will stall. | ||
