ma5 doesn't see the .hepmc event files on the reco level

Asked by Mustafa Ashry on 2019-02-09

Hi Benjamin,
I have two issues:
First, MG doesn't produce lhco files so that I can use them in ma5

Second, when i want to import a data set into ma5, it doesn't see the .hepmc event files on the reco level. I use the following command sequence
./bin ma5 -R
ma5>import samples_1/sm_tag_1_pythia8_events.hepmc.gz

and it gives the following error
MA5-ERROR: The dataset 'samples_1/sm_tag_1_pythia8_events.hepmc.gz' has not been found or has a unsupported format.

Any help will be appreciated

Mustafa

Hi Mustafa,

The hepmc file is not a reco file so that it is normal you cannot load it in the reco mode. Please have a look to
  https://arxiv.org/abs/1808.00480 <https://arxiv.org/abs/1808.00480>
to get more information on how to use ma5 on hepmc files in the reco mode (fastjet, delphes, recasting).

Regards,

Benjamin
