MCatNLO Step 1

We will produce MCatNLO events starting from scratch. In step 1 we will download the MCatNLO program, configure it to our needs and perform the integration step. Once that has been done, we will produce the executable that will be used later to generate events.

1) Prepare your working directory

(this dir will be referred to as /scratch/MyMCatNLO in future)

cd scratch
mkdir MyMCatNLO 

2)Download the package and the PDF libraries

Download the package

Go to the MCatNLO webpage and download the package (called Package231.tar.gz)

cd /scratch/MyMCatNLO
mkdir MyMCatNLO_EXECUTABLE
cd MyMCatNLO_EXECUTABLE

tar -xzvf Package231.tar.gz

Download the PDF libraries Go to the MCatNLO webpage and download the package (called grid-files)

mkdir PDF
cd PDF

Now download the pdf libraries that come with MCatNLO(data.tar) and untar them.

tar -xvf data.tar

Note: These libraries are simply ascii files and since MCatNLO is a NLO MC it requires NLO PDFs. For technical reasons we decided for the Rome production to use cteq5m1.
