| 3 | 3 | This page aims to outline how to use NEUT to create a sample of interactions on your favourite target. We'll also outline how to feed this generated sample through the NUISANCE framework and get good results. |

| | 6 | == Compiling NEUT and running neutsmpl == |
| | 7 | |
| | 8 | The main neutrino-nucleus interaction generator lives in src/neutsmpl/neutroot. NEUT has two dependecies: ROOT and the lesser known CERNLIB. You need to have $ROOTSYS, $CERN and $CERN_LEVEL environment variables set-up to compile NEUT. Compilation is done (somewhat inconveniently) by running ./Makeneutsmpl in src/neutsmpl/. This calls a host of makefiles, sets up symlinks and so on. If you want to fix this and have the time, please contact us or Hayato-san. |
| | 9 | |
| | 10 | Running the main executable is done by ./neutroot CARD_FILE.card OUTPUT_ROOT_FILE.root, where CARD_FILE.card is a card file compliant with your chosen NEUT version, and OUTPUT_ROOT_FILE.root is the output file where the events are to be saved. |
| | 11 | |
| | 12 | Hot tip: NEUT can be quite verbose and you might want to pipe the output to file (or /dev/null...) rather than dump it to screen. This can actually speed up NEUT considerably. |
