1 | 1. run.C is the main macro to use. It takes as an argument the raw-data run number to be reconstructed. |
2 | Note: don't forget to change the username there. |
3 | |
4 | 2. rec.C is called from run.C and does: |
5 | *) raw-data input is set to all the raw-data files from the run (rec.SetInput("raw://runXXX")) |
6 | *) QA is switched off due to high memory consumption, it can enabled in case one reconstructs less detectors. |
7 | *) rec.SetEventRange() is used to limit the time of the query. Can be changed according to the needs. |
8 | *) Output is a dataset, which one can setup by rec.SetOutput. The syntax is simple, just follow the example |
9 | and put a coma separated list of output root file just between the first : and @. For example one case do: |
10 | |
11 | root_archive.zip#AliESDs.root:AliESDs.root,AliESDfriends.root,MUON.RecPoints.root@dataset://runXXX |
12 | |
13 | wildcards should work, but better define explicit names. |
14 | The output is a normal CAF dataset (as the one staged from the grid). |
15 | |
16 | 3. prepareAlienCollection.sh is a helper script in case the run is long and one wants to select a subset |
17 | of files to bre reconstructed. The syntax is: |
18 | |
19 | ./prepareAliEnCollection.sh XXX XXX.txt |
20 | |
21 | Then rec.C should be changed, so that the input becomes 'collection://XXX.txt'. |
22 | Note: alien-token-init should be in the path. |
23 | |
24 | 4. rec.sh is a simple shell script which takes the run number as an argument and calls |
25 | 'aliroot run.C' |
