24 | // Class designed to convert raw data to aliroot format. We assume, that | |
25 | // prototype is situated in the center of 3 PHOS module and convert prototype | |
26 | // outpur to AliPHOSDigits. In addition, we fill branch of TreeE with | |
27 | // AliPHOSBeamTestEvent, contaning description of event(triggers etc). | |
28 | // Note, that one byte per channel in raw data is transvormed to class | |
29 | // AliPHOSDigit, so finale zise increase ~ 100 times. So output can be split | |
30 | // into peases of reasonable size: each file can not contain more than | |
31 | // fMaxPerFile: if there are still events in raw file, then new directory | |
32 | // is created and header+digits files are written to it. | |
33 | // | |
34 | // Use Case: | |
35 | // AliPHOSRaw2Digits * r = new AliPHOSRaw2Digits("path/input.file") ; | |
36 | // //note, that it can be gzipped file! | |
37 | // //Set position of the target in the given run. | |
38 | // //Z axis along beam direction, from target to prototype (0-surface of prototype) | |
39 | // //X axis along columns of prototype (0-center of prototype) | |
40 | // //Y axis along raws of prototype (0-center of prototype) | |
41 | // Double_t pos[3]={0,0,-452.} ; | |
42 | // r->SetTargetPosition(pos) ; | |
43 | // //Read/create connection Table: | |
44 | // TFile f("ConTableDB.root") ; | |
45 | // AliPHOSConTableDB * cdb = f.Get("AliPHOSConTableDB") ; | |
46 | // f.Close() ; | |
47 | // r->SetConTableDB(cdb) ; | |
48 | // r->ExecuteTask() ; | |
49 | // | |
50 | // As a result files galice.root and PHOS.Digits.root should be produced in | |
51 | // current dir, and, possibly, dirs 1,2,3... each with galice.root and PHOS.Digits.root, | |
52 | // where the rest of data are written. | |
