4+
First of all gather all the code and create all the directories.
5+
```
6+
mkdir TB_dir
7+
cd TB_dir
8+
mkdir -p data/VME/RAW
9+
mkdir data/VME/RECO
10+
mkdir data/Tracks
11+
mkdir data/NimPlus
12+
13+

git clone https://github.com/CaltechPrecisionTiming/DataQualityMonitor.git
15+
16+
cd TimingDAQ
17+
make -j8
18+
cd -
19+
```
20+
21+
Copy in the proper data folder all the necessary collected data.
22+
23+
## Decode the raw data and create root files
24+
25+
Create config files to run on the desired channels. A new version of config files is supposed to be created for each different set of analysis (i.e. whenever the analyzed channel content is not consistent).
26+
Two config files need to be created and placed in the proper directories. One for ``TimingDAQ`` with the name ``VME_<v>.config`` (like this one [here](https://github.com/CaltechPrecisionTiming/TimingDAQ/blob/master/config/FNAL_TestBeam_1811/VME_vr3.config)) and on for the DQM with the name ``VME_<v>.txt`` (like this one [here](https://github.com/CaltechPrecisionTiming/DataQualityMonitor/blob/master/config/FNAL_TB_1811/VME_vr3.txt)), where ``<v>`` is the version name. The standard is to use ``v<N>`` for TB versions and ``vr<N>`` for post TB versions, where ``<N>`` is an increasing number.
27+
When creating the ``TimingDAQ`` config make sure that it is placed in the same directory stated [here](https://github.com/CaltechPrecisionTiming/TimingDAQ/blob/master/automation/DecodeData.py#L14).
