This is an attempt to use Les Houches event files to generate an event in Herwig.
We target the inclusive dijet production event at 7 TeV, using an LHE file from MadGraph5.
Please make a folder and copy the input and LHE files in it;
Input file:
{F541661}
LHE file:
{F541662}
Alternatively, you can simply use the following commands:
```
mkdir LesHouches
cd LesHouches
wget https://phab-files.hepforge.org/file/download/n5ycv7s67f47i7nk37fi/PHID-FILE-bzz3zr7ar5bniyuqmct5/LHC-LesHouches.in
wget https://phab-files.hepforge.org/file/download/ktmalsrogbl4ec52dynp/PHID-FILE-73dmncv2ytrteho6g3gn/LHC-dijet.lhe.gz
```
Now, you can run the event by:
```
Herwig read LHC-LesHouches.in
Herwig run LHC-LesHouches.run -N 10000
```
By looking at the input files, one finds out that it is using the [[https://rivet.hepforge.org/analyses/ATLAS_2012_I1082936.html | ATLAS_2012_I1082936 ]] Rivet analysis plugin to compare the results against the exiting experimental data. To create the corresponding plots, run:
```
rivet-mkhtml LHC-LesHouches.yoda
```
and find the plots in "rivet-plots" directory.
Obviously, 10000 iterations are not nearly enough to cancel-out the statistical fluctuations in the results. However, running this event with the minimum of the required iterations could be time-consuming. We have already run this event for 8 million iterations:

you can compare your results with our's, using
```
rivet-mkhtml LHC-LesHouches.yoda:N10K dijet7TeV.yoda:N8M
```
