af8e1c2d 36 /*******************************************************************
37 * This macro displays geometrical information related to the
38 * hits, digits and rec points in ITS.
39 * There are histograms that are not displayed (i.e. energy
40 * deposition) but that are saved onto a file (see below)
41 *
813e97e8 42 * INPUT arguments:
43 *
44 * Int_t evesel: the selected event number. It's =0 by default
45 *
af8e1c2d 46 * Options: Any combination of:
47 * 1) subdetector name: "SPD", "SDD", "SSD", "All" (default)
48 * 2) Printouts: "Verbose" Almost everything is printed out:
49 * it is wise to redirect the output onto a file
813e97e8 50 * e.g.: .x AliITSGeoPlot.C("All+Verbose") > out.log
af8e1c2d 51 * 3) Rec Points option: "Rec" ---> Uses Rec. Points (default)
52 * otherwise ---> uses hits and digits only
53 * Examples:
813e97e8 54 * .x AliITSGeoPlot(); (All subdetectors; no-verbose; no-recpoints)
55 * .x AliITSGeoPlot("SPD+SSD+Verbose+Rec");
56 *
88cb7938 57 * filename: It's "galice.root" by default.
813e97e8 58 * isfastpoints: integer. It is set to 0 by defaults. This means that
59 * slow reconstruction is assumed. If fast recpoint are in
60 * in use, isfastpoints must be set =1.
61 * BEWARE: to analyze digits/recpoints produced with aliroot
62 * versions older than v3-07-Release, the input parameters
63 * filename, FileDigits, FileRec and isfastpoints must be left
64 * to their default value
af8e1c2d 65 *
66 * OUTPUT: It produces a root file with a list of histograms
813e97e8 67 *
af8e1c2d 68 * WARNING: spatial information for SSD/DIGITS is obtained by pairing
69 * digits on p and n side originating from the same track, when
70 * possible. This (mis)use of DIGITS is tolerated for debugging
71 * purposes only !!!! The pairing in real life should be done
72 * starting from info really available...
73 *
74 * COMPILATION: this macro can be compiled.
813e97e8 75 * 1) You need to set your include path with
af8e1c2d 76 * gSystem->SetIncludePath("-I- -I$ALICE_ROOT/include -I$ALICE_ROOT/ITS -g");
77 * 3) If you are using root instead of aliroot you need to
78 * execute the macro loadlibs.C in advance
79 * 4) To compile this macro from root (or aliroot):
813e97e8 80 * --- .L AliITSGeoPlot.C++
81 * --- AliITSGeoPlot();
