7 | \section eve_s1 The EVE event display | |
8 | ||
9 | This README file shows how to use the EVE event display for the MUON detector. | |
10 | The explained procedure is a complement to the visualisation of the full ALICE | |
11 | detector discussed on the ALICE Offline page, "Visualisation": | |
12 | http://aliceinfo.cern.ch/Offline/Activities/Visualisation/ | |
13 | ||
14 | \subsection eve_s1_sub1 Macros for the event display | |
15 | ||
16 | Found in $ALICE_ROOT/EVE/alice-macros and $ALICE_ROOT/EVE/macros. | |
17 | - MUON_displaySimu.C , to be used with simulations (shows also reference | |
18 | tracks, Monte-Carlo tracks and hits) | |
19 | - MUON_displayData.C , to be used with reconstructed raw data (with the option | |
20 | SAVEDIGITS in the reconstruction, "simulation" digits are also produced and | |
21 | can be visualized) | |
22 | - alieve_init.C , initialisation of the EVE environment | |
23 | - event_goto.C , navigation in the tree of events | |
24 | - geom_gentle_muon.C , draws a "light" geometry of the MUON detector obtained | |
25 | from the sensitive volumes of all MUON chambers; the default geometry of the | |
26 | event display is made of contours of the chambers extracted from the mapping | |
27 | ||
28 | \subsection eve_s1_sub2 Usage | |
29 | ||
30 | - launch the "alieve" executable | |
31 | ||
32 | <pre> | |
33 | alieve | |
34 | </pre> | |
35 | ||
36 | - load the following macros (.L macro.C) | |
37 | ||
38 | <pre> | |
39 | alieve_init.C | |
40 | event_goto.C | |
41 | MUON_displayData.C | |
42 | or | |
43 | MUON_displaySimu.C | |
44 | geom_gentle_muon.C | |
45 | </pre> | |
46 | ||
47 | - initialize the EVE environment with your data | |
48 | ||
49 | <pre> | |
50 | alieve_init("directory_to_data",event_number) | |
51 | </pre> | |
52 | ||
53 | - display the current event | |
54 | ||
55 | <pre> | |
56 | MUON_displaySimu(0,0) - do not show tracks | |
57 | MUON_displaySimu(0,1) - show tracks | |
58 | MUON_displaySimu(1,0) - do not tracks, read digits from produced raw data | |
59 | MUON_displaySimu(1,1) - show tracks, read digits from produced raw data | |
60 | MUON_displayData(1,0) - do not show tracks | |
61 | MUON_displayData(1,1) - show tracks | |
62 | MUON_displayData(0,0) - do not show tracks, read the saved digits | |
63 | MUON_displayData(0,1) - show tracks, read the saved digits | |
64 | </pre> | |
65 | ||
66 | - draw the "gentle" geometry (sensitive volumes) | |
67 | ||
68 | geom_gentle_muon() | |
69 | ||
70 | - navigate in the event list | |
71 | ||
72 | event_goto(n) | |
73 | ||
74 | - Shift + right mouse button one a muon track opens the context menu (track | |
75 | and trigger information is available) | |
76 | ||
77 | - a new flag argument is added to the MUON_display macros for displaying the | |
78 | the clusters taken from the ESD (default), only those attached to the tracks, | |
79 | or from MUONRecPoints, all reconstructed clusters | |
80 | ||
81 | <pre> | |
82 | MUON_displaySimu(x,x,1) - clusters from ESD | |
83 | MUON_displaySimu(x,x,0) - clusters from rec points | |
84 | MUON_displayData(x,x,1) - clusters from ESD | |
85 | MUON_displayData(x,x,0) - clusters from rec points | |
86 | </pre> | |
87 | ||
88 | This chapter is defined in the READMEeve.txt file. | |
