0049 ## INTT DST production
0050 To run the INTT DST production, do
0051 ```
0052 python InttMbdCombineChain.py --inttdst
0053 ```
0054 The script will do the following steps:
0055 1. Check whether the [sPHENIX macro repository](https://github.com/sPHENIX-Collaboration/macros/tree/master) exists under the `[softwarebasedir]` directory (`[softwarebasedir]` is specified in the configuration `config_combinechain.py`). If yes, it will pull the latest version of the repository. If not, it will clone the repository.
0056 2. Change the directory to `[softwarebasedir]/macros/InttProduction`, and modify the `runTrkrHits`, `runTkrkClus`, `stripRawHit` flags in `Fun4All_Intt_Combiner.C` according to the flags `[inttdstproduction_runTrkrHits]`, `[inttdstproduction_runTkrkClus]`, and `[inttdstproduction_stripRawHit]` in `config_combinechain.py`.
0057 3. Execute the `intt_makelist.sh` under `[softwarebasedir]/macros/InttProduction` to produce INTT raw data lists of the given run number `[runnumber]`.
0058 4. Run the macro `Fun4All_Intt_Combiner.C` to produce the INTT DST. You could change `inttdstproduction_InttUnpacker_nEvt` to a number other than -1 for testing purpose. If it is set to -1, the macro will process all events.
0059 4. After the INTT DST production is done, the script will clean up the INTT raw data lists and move the INTT DST to the `[productiondir]` directory (`[productiondir]` is specified in `InttMbdCombineChain.py`).
0060
0061 ## INTT ntuple production
0062 To run the INTT ntuple production, do
0063 ```
0064 python InttMbdCombineChain.py --inttntuple
0065 ```
0066 The script will do the following steps:
0067 1. Check whether the INTT DST `[productiondir]/intt-[runnumber].root` exists. If not, it will try to copy the pre-generated DST under `/gpfs/mnt/gpfs02/sphenix/user/cdean/software/macros/InttProduction/`. If there is no pre-generated DST, the script will exit.
0068 2. Change the directory to `[dndetamacrodir]/condor/` (`[dndetamacrodir]` is specified in `config_combinechain.py`).
0069 3. Run the `runCondor.py` to submit condor jobs to produce the INTT ntuples. (See [runCondor.py](https://github.com/sPHENIX-Collaboration/analysis/blob/master/dNdEta_Run2023/macros/condor/runCondor.py) for more details).
0070 4. The INTT ntuples will be stored under `[productiondir]/[inttntupleproduction_InttNtupleDir]`.
0071
0072 ## Centrality and minimum-bias ntuple production
0073 To run the centrality and minimum-bias ntuple production, do
0074 ```
0075 python InttMbdCombineChain.py --centmbntuple
0076 ```
0077 The scripts will do the following steps:
0078 1. Change the directory to `[dndetamacrodir]`.
0079 2. Execute the sPHENIX pre-built script `CreateDstList.pl` to produce the calorimeter DST lists with the given `[runnumber]`, the sPHENIX software version `[centntupleproduction_softwareversion]`, and the production tag `[centntupleproduction_productionTag]`.
0080 3. Change the directory to `[dndetamacrodir]/condor/`.
0081 4. Run the `runCondor.py` to submit condor jobs to produce the centrality and minimum-bias ntuple. (Note: You should run a single condor job for the centrality and minimum-bias ntuple production, as the centrality and minimum-bias ntuple production is not parallelizable)
0082 5. The centrality and minimum-bias ntuples will be stored under `[productiondir]/[centntupleproduction_CentralityNtupleDir]`.
0083
0084 ## INTT-MBD event combiner
0085 To run the INTT-MBD event combiner, do
0086 ```
0087 python InttMbdCombineChain.py --runcombiner
0088 ```
0089 The script will do the following steps:
0090 1. Merge the INTT ntuples. The merged INTT ntuples will be stored under `[productiondir]/[inttntupleproduction_InttNtupleDir]`.
0091 2. Run the INTT-MBD event combiner `intt_mbd_evt_combiner_v1.py`. See [INTT_MBD_evt_combiner repository](https://github.com/sPHENIX-Collaboration/analysis/tree/master/INTT_MBD_evt_combiner) for more details.
