A new Pull Request was created by @syuvivida for CMSSW_7_3_X. Codes required to do multiple hadronization and to print out cross section including HepMCFilter efficiency It involves the following packages: GeneratorInterface/Core The following packages do not have a category, yet: GeneratorInterface/HepMCFilters @vciulli, @covarell, @thuer, @cmsbuild, @nclopezo, @bendavid can you please review it and eventually sign? Thanks. |

The new package here is GeneratorInterface/HepMCFilters which defines a new interface (plus first implementation) for HepMCFilters which allow to filter on the HepMCEvent inside the hadronizer loop. (So a reasonable sized lhe sample can be used together with hadronization-level filters) |
|
@bendavid - could the files in the new package just go to Gen.../Core (which in any case depends on the new package) - unless you are expecting this new package to grow a lot, it seems a practical solution. |
|
@davidlange6 we expect that this package will be updated relatively more frequently than GenInterface/Core as new filters are added. (Any new filter intended to be used with an lhe-based request will have to be added here.) There was a discussion about this by mail some months ago which I will re-forward. (It took some time to properly test and converge on the final pull request since then.) |
|
Seeing that now most of the GenInterface/Core filters now depend on the new package, I would prefer to use the Core package until we see the pace of new filters being added unless there is a dependency issue that I'm missing (as in any case, we'll have to checkout and recompile Core when these others are updated) |
|
So indeed the reason to make a new package instead of putting everything in Core was organizational rather than technical. I'll move things back into Core since that seems to be preferred. |

The code change includes
Josh's update which allows input lhe files to be hadronized multiple times in
order to boost the matching/filter efficiency.
Eiko's update in GenXSectionAnalyzer, HadronizerFilter, and HepMCFilterDriver:
Additional GenFilterInfo with process name = "generator" is saved so to retrieve the filter efficiency of HepMCFilter and to compute cross section correctly.
