Easy GRETINA Decomp File Creation

create a new directory ~gretina/DecompParam/detmap_YYMMD

copy your detmap files for the individual quads to the new directory (standard format: detmap_Q1.txt)

run the script ~analysis/packages/Calibrations/apply_calibration_steps.sh <dirname>

~analysis/packages/Calibrations/apply_calibration_steps.sh .

assuming the 10 detmap file exists, this script will create all the necessary decomp files for all gain ranges using the standard naming conventions.

You may need to edit the trace gain file for broken segments (i.e. Q4P2, tr_gain_Q4pos2_CC9.txt, set line 25 to 10000.0 and Q8P2 gamma6, line 19 ) OR give SMALL calibration parameter in the detmap_Qx.txt file.

Loading the Decomp Files

Copy the setfile. The setfiles are located in ~gretina/DecompParam/ Copy the last setfile to the current date:

cp setFile.2017-02-09 setFile.YYYY-MM-DD

Edit the newly created setfile. Perform a search and replace within the new setfile of the old date and replace it with the new date; example using setfile.2017-02-09 one would change:

170209  ->  YYMMDD

edit the file ~/grdecomp.sh to point to the new setfile. This is done by editing the variable FILECONF in ~/grdecomp.sh This variable will be the first uncommented line in the file. Best practice is to copy/comment the original line before editing.

Restarting GRETINA Decomp

Once the above steps are complete, the decomp process needs to be restarted. This can be done in one of two ways:
- Press either the GRETINA Stand Alone of GRETINA + S800 button.
- or run ./grdecomp.sh from a terminal connected to a2.gam (WARNING: this will open the run dialog box on the computer the terminal is open on.)
