The IVF will run out-of-the-box in CMSSW_5_3_11. If unsure, you can check out the following two packages:
cvs co -r V02-02-06 RecoVertex/AdaptiveVertexFinder cvs co -r V01-10-02 RecoBTag/SecondaryVertex
For a very low-level analysis (which is also partly outdated and therefore not recommended) need to check out two additional packages:
#cvs co -d IVF/BCandidateProducer UserCode/BbCorrelation/CMSSW/BAnalysis/BCandidateProducer #cvs co -d ZSV/BAnalysis UserCode/ZSV/BAnalysis/ #scram b -c
Last command needed to update really old IVF package config files to BuildFile.xml files.
In order to get the IVF to work one has to perform inclusive vertexing by including inclusiveVertexing_cff.py:
process.load('RecoVertex/AdaptiveVertexFinder/inclusiveVertexing_cff')
The IVF runs on pre-selected vertices. These are selected using the inclusive vertex finder from the adaptive vertex finder package:
These vertices are then merged depending on their significance in distance and the fraction of tracks they share:
