To use for example version v1.2.2 of the NA62FW from CVMFS, on a CC7 machine, we set the environment with
source /cvmfs/na62.cern.ch/offline/NA62FW/prod/v1.2.2/NA62Analysis/scripts/env.sh
Validation Step 1 is run with a list of reconstructed files as input (download the linked files first)
PostProcessing -l filelist.txt -e1 -o Step1.root --config PostProcessing.conf
and Step 2 takes as input the root file produced at Step 1:
PostProcessing -i Step1.root -e1 --histo
This will produce a lot of files, something like this
The plots produced by the example above are the default set, however, the list of analysers and the plots produced are customisable.
