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 program itself
cd /scratch/MyMCatNLO mkdir MyMCatNLO_EXECUTABLE cd MyMCatNLO_EXECUTABLE
Go to the MCatNLO webpage and download the package (called Package231.tar.gz). Then untar it.
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
Go to the MCatNLO webpage and download the pdf librarie sthat come with MCalNLO. (On the web-page they are listed as: grid files). Then untar it.
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.
3) Tailor the MCatNLO program to your wishes
Since we will not use th MonteCarlo option (i.e. we do not want the package to call Herwig since we will do that ourselves later inside the ATLAs software). The most important file in that case is MCatNLO.inputs
