MCatNLO howto

Running MCatNLO

This page describes how to produce simulated events in the ATLAS detector using the MCatNLO generator. The page is set up so that you can start from scratch, but since most people will produce many events some python scripts have been added that were used for the Rome production. These scripts are not brilliant, but should be used as a guideline for future use.

Step-by-step guideline

Producing events in ATLAS can be split up in three separate steps:

1. MCatNLO Integration step and producing the executable (standalone)
2. Generating events (standalone)
3. Top decay and producing an ntuple using Atlfast (athena)
