For the kaon acceptance calculations, you will a few CLAS6 software packages such as gsim, gpp, and a1c.
Getting Started
- Install the CLAS6 software packages. This will get complicated, so take some time to read through the various instructions on the CLAS wiki pages mentioned below.
- Follow the link on the CMENP sidebar to Hall B
- Click on the tab for CLAS
- Follow the link for Offline Data Analysis under the Analysis Software section in the lower right corner of the page.
- In the list of Contents, go to the section labeled CLAS Software System Documentation.
- Read the items labeled Building CLAS Software and Build CLAS Software: more detailed instructions. Read the various subsections in each of these items.
- Since you will be the only person using your Linux computer, I recommend building the software in your home directory. To do this, start in the top of your home directory by using the command
- cd $HOME
- Follow the instructions for Checking out entire clas6 software suite under Build CLAS Software: more detailed instructions.
- There will be many questions and mistakes, but this is a learning process. Take your time.
- After the CLAS software suite has been compiled, check that the programs gsim, gpp, and a1c are working. You can do this by typing the command gsim -h or a1c -h, and you should see a help menu in the terminal.
The Chain of Programs to Calculate Acceptance
To calculate the CLAS detector acceptance, you will run a series of programs in order. They are
- Your PLUTO++ reaction generator.
- A text to BOS converter. BOS is the data format of CLAS6.
- gsim - detector simulator
- gpp - post-processing program
- a1c - physics analysis program
Scripts will be provided that will run each of these programs automatically.
