scram b -j20

open  PhysicsTools/PatUtils/python/patPFMETCorrections_cff.py and uncomment the lines about type0 corrections: lines 99,100,74,64 
open  PhysicsTools/PatAlgos/python/producerLayer1/jetProducer_cfi.py  and comment lines 49-53, otherwise the pattificator will not work on the official MC samples 
To use JEC, JER and JEC uncertainties download this .zip file from here https://github.com/cms-cvs-history/CondFormats-JetMETObjects, build and complile a directory named CondFormats/JetMETObjects 
git cms-addpkg JetMETCorrections/Objects
scram b -j20

Insert Hplus code in the environment:

1. Pattificator

Take directories pat_* and place them under TopQuarkAnalysis/TopPairBSM 

2. Analyzer 

Take the HplusCode_v5 directory from this github repository and place it in PhysicsTools, compile it with scram b

3. Offline analysis
You can find it in the offline_analysis directory. It runs on the final ntuples, produces plots and datacards for combined. 

4. Combine
Follow instructions here to set up the environment on lxplus:
https://twiki.cern.ch/twiki/bin/viewauth/CMS/SWGuideHiggsAnalysisCombinedLimit#Setting_up_the_environment

Take limits directory and place it in CMSSW_7_4_7/src/HiggsAnalysis/CombinedLimit/data. Add there the datacards produced with the offline analysis to compute blinded limits. 
For unblinded results, do he same with limits_unblinded directory.
