8 | macro to create array of clusters from TPC digits | |
9 | input files - galice.root | |
10 | digits.root - file with digits - usualy use link to galice.root | |
11 | - in splitted mode - neccesary to create link to proper file | |
12 | ||
13 | output file - TPC.RecPoints.root | |
14 | ||
15 | ||
16 | // Warning - if cluster file AliTPCclusters.root already exist - macro exit and don't produce anything | |
