18f5e673 | 7 | This README file shows how to use both the old and new EVE event display for |
8 | the MUON detector. The explained procedure is a complement to the visualisation | |
9 | of the full ALICE detector discussed on the ALICE Offline page, "Visualisation": | |

13 | ||
14 | \subsection eve_s1_sub1 Macros | |
bc694317 | 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 | |

122 | Execute from aliroot the macro MUONGenerateGentleGeometry.C and place the resulting file in EVE/alice-data. This file is used by the macro geom_gentle_muon.C | |
123 | from EVE/alice-macros. | |
