4d24e763 | 18 | Revision 1.5 2002/05/13 14:27:57 hristov |
19 | TreeC created once per event (M.Masera) | |
20 | ||
def15085 | 21 | Revision 1.4 2002/05/10 22:31:30 nilsen |
22 | Changes by Massimo Masera to allow Recpoints and Clusters to be written | |
23 | to separate files. | |
24 | ||
f243fbe6 | 25 | Revision 1.3 2002/02/06 13:52:27 barbera |
26 | gAlice deletion corrected (from M. Masera) | |
27 | ||
8f9d0004 | 28 | Revision 1.2 2002/01/31 18:52:09 nilsen |
29 | Minor change to allow the use of files that are already open. grun.C macro | |
30 | that also does ITS digitizationa and Reconstruction all in one go. | |
31 | ||
3e9ba728 | 32 | Revision 1.1 2002/01/30 22:20:22 nilsen |
33 | New TTask based method to do Digits To clusters. Works with files of multiple | |
34 | events in the file. Macro added to show how to use. Also the changes made | |
35 | in the nessesary complilation files. | |
