19 // Class designed to convert raw data to aliroot format. We assume, that
20 // prototype is situated in the center of 3 PHOS module and convert prototype
21 // outpur to AliPHOSDigits. In addition, we fill branch of TreeE with
22 // AliPHOSBeamTestEvent, contaning description of event(triggers etc).
23 // Note, that one byte per channel in raw data is transvormed to class
24 // AliPHOSDigit, so finale zise increase ~ 100 times. So output can be split
25 // into peases of reasonable size: each file can not contain more than
26 // fMaxPerFile: if there are still events in raw file, then new directory
27 // is created and header+digits files are written to it.
30 // AliPHOSRaw2Digits * r = new AliPHOSRaw2Digits("path/input.file") ;
31 // //note, that it can be gzipped file!
32 // //Set position of the target in the given run.
33 // //Z axis along beam direction, from target to prototype (0-surface of prototype)
34 // //X axis along columns of prototype (0-center of prototype)
35 // //Y axis along raws of prototype (0-center of prototype)
36 // Double_t pos[3]={0,0,-452.} ;

39 // TFile f("ConTableDB.root") ;
40 // AliPHOSConTableDB * cdb = f.Get("AliPHOSConTableDB") ;
42 // r->SetConTableDB(cdb) ;
45 // As a result files galice.root and PHOS.Digits.root should be produced in
46 // current dir, and, possibly, dirs 1,2,3... each with galice.root and PHOS.Digits.root,
47 // where the rest of data are written.
