0001 ### How to produce a calibration file for ClusterShapeHitFilter
0002
0003 1. Copy the cfg file in your area
0004
0005 ```shell
0006 cp $CMSSW_RELEASE_BASE/src/RecoTracker/PixelLowPtUtilities/test/clusterShapeExtractor_phase* .
0007 ```
0008 2. Get the list of files from relval and substitute to those in the file in the release
0009 3. cmsRun it: it create a root file named _clusterShape.root_
0010 4. Produce a calibration file:
0011
0012 ```shell
0013 clusterShapeAnalyzer --input clusterShape.root --output myClusterShape.par
0014 ```
0015 5. you can produce also a calibration file w/o taking BPIX1 into account : just change
0016 ```code
0017 process.clusterShapeExtractor.noBPIX1=False
0018 ```
0019 to
0020 ```code
0021 process.clusterShapeExtractor.noBPIX1=True
0022 ```
0023
0024 6. Analysis the resulting file using/modifing the pcsfVerify.ipynb notebook
0025 7. to use the produced file(s) edit RecoTracker/PixelLowPtUtilities/python/ClusterShapeHitFilterESProducer_cfi.py
