#266 closed question (fixed)

Outputting generated events into .root file

Reported by: sd544@cam.ac.uk Owned by: support@sherpa-mc.de
Priority: major Milestone: rel-2.0.0
Component: Unknown Version: 2.0.beta2
Keywords: root, output Cc:

Description

I am running Sherpa with one of the Example runcards (Examples/Jets_at_LeptonColliders/LEP_Jets_MCatNLO/Run.dat) and I have added the following line to the (run) section of the runcard:

EVENT_OUTPUT=Root[trialEvent]

in order to produce an output Root file. However, even if the file is produced this is emtpy and the following error is reported by Sherpa (after the second run): Sherpa: Output_RootNtuple::Output throws fatal error:

Error in NLO type

Exception_Handler::GenerateStackTrace(..): Generating stack trace {

0x2ac12755ef10 in 'ATOOLS::Terminate()' (Exception_Handler.C:216) 0x402ee2 in 'main' (Main.C:72)

}

how can I fix this? Best regards,

Stefano

Dear Stefano,

you can generate Root NTuples only for fixed-order calculations. In your case, please use HepMC2 or HEPEVT output.

Best Stefan
