fNLO and LHE files

Hi,

No.

This can likely be done at the post-processing stage when the various file are merged together.
You can probably forbid that step to keep all file separated. But you need to hack the code for doing that.

That's depend of the cut that you specify in the run_card. We do have default cut in that file.

The full information on all the functionality related to lhef for f(N)LO is present in this thread:
