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.

• 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.

• 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.)
