MCatNLO howto

Running MCatNLO

This page describes how to generate events in the ATLAS detector using the MCatNLO generator. The description is set up for 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.

The three steps to success when using MCatNLO

Producing events in ATLAS using MCatNLO 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)
