a7a1dd76 1/// \file FindKrClusters.C
2/// \brief Macro to create array of clusters from TPC digits
3///
4/// Input files:
5///
6/// * galice.root
7/// * digits.root: file with digits - usualy use link to galice.root
8/// in splitted mode - neccesary to create link to proper file
9///
10/// Output file:
11///
12/// * TPC.RecPoints.root
13///
14/// Warning - if cluster file AliTPCclusters.root already exist - macro exit and don't produce anything
15///
