24 | // Usage: | |
25 | // You can create the AliEMCALGeoUtils object independently from anything. | |
26 | // You have to use just the correct name of geometry. If name is empty string the | |
27 | // default name of geometry will be used. | |

0c5b726e | 30 | // TGeoManager::Import("geometry.root"); |
31 | // | |
32 | // MC: If you work with MC data you have to get geometry the next way: | |
33 | // == ============================= | |
34 | // !!!!!!!!! This part has to be modified | |
35 | // AliRunLoader *rl = AliRunLoader::GetRunLoader(); | |
