Problem generating events from NLO tarball

Asked by Alexis Kalogeropoulos

Hello

After creating successfully an NLO tarball, I am trying to generate events, but that fails [1]. However, with the exact same machine setup, generating events from the LO tarball for the same process runs fine. I am using 2.6.7. I even tried to explicitly define the fortran path in the Cars/amcatnlo_configuration.txt etc but that did not solve the problem.

Thanks in advance
Alexis

Hi,

2.6.7 is out of support. If you like "old" version I would suggest to use 2.9.x which is our long term stable version (latest bug fix is 2.9.12).

I'm sorry but from the log, I have no clue on what the issue might be so the best is really to switch to either 2.9.12 or 3.4.1

Cheers,

olivier
