Added last decoder version (V2) in TOF raw data visualization

[u/mrichter/AliRoot.git] / EVE / alice-macros / ana_list_load_kinks.C

// Launches the list analyser and loads kinks into the list.
// If you already have a list (or rather a list analyser) with objects and you want to add the kinks to this list, do the following:
// Right-click the list analyser in the eve-browser and select "ExportToCint". Choose e.g. "list" for the name in the window that pops up.
// In the console type ".x ana_list_load_kinks.C(list)"
// For more information please see "ana_list.C" or have a look at the class documentation.
