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For a very low-level analysis (which is also partly outdated and therefore not recommended) need to check out two additional packages: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.

The IVF runs on pre-selected vertices. These are selected using the inclusive vertex finder from the adaptive vertex finder package:

• Source code: InclusiveVertexFinder.cc
• Configuration file: inclusiveVertexFinder_cfi.py
