 The production tools allow you to generate a plethora of processes (links lead to implementation in CMSSW):

+
+# This is the shell script that will generate all the skeletons using cmsDriver commands.
+# The commands included have been taken from runTheMatrix with the following command:
+#
+# runTheMatrix.py -w upgrade -l 20634.0 --command="--no_exec" --dryRun
+#
+# The reconstruction as part of the ticl framework is injected into the RECO_fragment.
+#
+# For all commands remove --filein and --fileout options.
+# Add python_filename option
+#
+# The first command combines step1 and step2 (GSD):
+# - mix in pileup
+# - run up to DIGI...HLT:@fake2
+# The following changes are implemented on top:
+# --beamspot HLLHC14TeV ➜ --beamspot NoSmear
+# --eventcontent FEVTDEBUG ➜ --eventcontent FEVTDEBUGHLT
+# Removed --relval option.
+#
+# The second command is step3 removing overlap with step2 (RECO):
+# - remove pileup part
+# - remove MINIAODSIM from event content and data tier
+# - remove PAT from steps (-s)
+# - remove @miniAODValidation from VALIDATION step
+# - remove @miniAODDQM from DQM step
+#
+# The third command is a copy of the second only re-running RECO (for NTUP):
+# - remove DQM from event content
+# - remove DQMIO from data tier
+# - add --processName=NTUP option
+#
+# Those commands should be regularly checked and, in case of changes, propagated into this script!
