7 \section eve_s1 The EVE event display
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/
14 \subsection eve_s1_sub1 Macros for the event display
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
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
28 \subsection eve_s1_sub2 Usage
30 - launch the "alieve" executable
36 - load the following macros (.L macro.C)
47 - initialize the EVE environment with your data
50 alieve_init("directory_to_data",event_number)
53 - display the current event
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
66 - draw the "gentle" geometry (sensitive volumes)
70 - navigate in the event list
74 - Shift + right mouse button one a muon track opens the context menu (track
75 and trigger information is available)
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
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
