Updated a bit with:

[u/mrichter/AliRoot.git] / FLOW / AliFlowCreatePico.C

//
// This macro is a part of "Alice PPR fast flow analysis package"
// 
// The macro creates new pico DST structure in the file 
// "flowPiocEvent.root" and create structure "flowData" inside
// 
// Once Ntuple is created it can be filled with data using  
// macro AliFlowReconstruction.C
