e727d2f7 | 1 | How to run one iteration of the pi0 calibration in the GRID: |
2 | ============================================================ | |
3 | ||
4 | Step 1 (aliensh) | |
5 | ||
6 | - copy the whole content of this directory (don't forget .roorc!) to your alien directory; | |
7 | - put pi0Select.sh to your ~/bin alien directory; | |
8 | - submit jobs from alien shell: submit Pi0Select.jdl | |
9 | This will launch the analysis of ~2*10**6 pp min bias events from the | |
10 | minbias_LHC09a4_81040_81050.xml collection. To analyze your own collection, update Pi0Select.jdl | |
11 | and AnaPi0Select.C accordingly. | |
12 | ||
13 | ||
14 | Step 2 (local directory) | |
15 | ||
16 | - Copy PHOS.tgz in this directory to your local directory; | |
17 | - Run tar xzf PHOS.tgz | |
18 | ||
19 | WARNING: Run this after the _first_ iteration only!! | |
20 | ||
21 | - merge the outputs of the analysis jobs (files histos.root) to the file Sum_All_Emc.root | |
22 | (use macro addhistoEmc.C if needed) and copy this file to your local directory; | |
23 | - Run pi0Calib.C script to calculate the corrections to the calibration coefficients: | |
24 | root -b -q pi0Calib.C | |
25 | - directory PHOS/Calib/EmcGainPedestals/ will contain the corrections to the calibration | |
26 | coefficients to run the next iteration; | |
27 | - Run tar czf PHOS.tgz PHOS and copy PHOS.tgz to your alien directory. | |
28 | ||
29 | For next iteration go to Step 1. | |
30 | -------------------------------- | |
31 | ||
32 | ||
33 | Useful files: | |
34 | ============= | |
35 | ||
36 | - use anaTask.C to run analysis locally. The list of ESD files to analyze is: list.txt. | |
37 | - for algorithm description and feasibility studies look at the presentation: | |
