3a4edebe | 6 | /// * galice.root |
a7a1dd76 | 7 | /// * digits.root: file with digits - usualy use link to galice.root |
8 | /// in splitted mode - neccesary to create link to proper file | |

10 | /// Output file: | |
11 | /// | |
12 | /// * TPC.RecPoints.root | |

14 | /// Warning - if cluster file AliTPCclusters.root already exist - macro exit and don't produce anything | |
