! This file contains commands to be read in for a Pythia8 run.
! Lines not beginning with a letter or digit are comments.
! Names are case-insensitive  -  but spellings-sensitive!
! The settings here are illustrative, not always physics-motivated.

! 1) Settings used in the main program.
Main:timesAllowErrors = 3          ! how many aborts before run stops

! 2) Settings related to output in init(), next() and stat().
Init:showChangedSettings = on      ! list changed settings
Init:showChangedParticleData = off ! list changed particle data
Next:numberCount =   0             ! print message every n events, 0 = off
Next:numberShowLHA = 1             ! print LHA information n times
Next:numberShowInfo = 1            ! print event information n times
Next:numberShowProcess = 1         ! print process record n times
Next:numberShowEvent = 0           ! print event record n times

! 3) Other common settings.
6:m0 = 175.                        ! same m_t as in the LHEFs

! 4) The number of subruns to execute.
Main:numberOfSubruns = 2

! 5) Information specific to the first subrun
Main:subrun = 1                    ! matches readFile( ..., 1)
Beams:frameType = 4                ! use LHEF input
Beams:LHEF = ttbar.lhe             ! first LHEF event file

! 6) Information specific to the second subrun
Main:subrun = 2                    ! matches readFile( ..., 2)
Beams:newLHEFsameInit = on         ! no reinitialization needed/wanted
Beams:LHEF = ttbar2.lhe            ! second LHEF event file
