Hi, I'm trying to run an external LHE file produced with POWHEG through the pythia+delphes framework in Madgraph (v 5.1.5.15). I copy the LHE file to a run_01 directory and rename it unweighted_events.lhe and then gzip it. Then I run pythia on it but get the following error: At line 148 of file ME2pythia.f Fortran runtime error: Bad integer for item 1 in list input 1 I think its not able to read the LHE file. When I run over an LHE file produced by Madgraph then everything works fine. The LHE file from POWHEG that I'm trying to run over is below. Any suggestions on what the problem might be and how I can modify the LHE file so its readable? Thanks Sarah ----------------------------------------- 2212 2212 4.00000E+03 4.00000E+03 -1 -1 -1 -1 -4 1 -1.00000E+00 -1.00000E+00 1.00000E+00 10001 7 10001 3.42641E-05 3.94731E+01 -1.00000E+00 1.48520E-01 4 -1 0 0 511 0 0.000000000E+00 0.000000000E+00 6.502557531E+01 6.502557531E+01 0.000000000E+00 0.00000E+00 9.000E+00 -4 -1 0 0 0 502 0.000000000E+00 0.000000000E+00 -1.395013273E+03 1.395013273E+03 0.000000000E+00 0.00000E+00 9.000E+00 23 2 1 2 0 0 2.589726567E+01 5.611445066E+01 -6.206042143E+02 7.229823010E+02 3.656970287E+02 0.00000E+00 9.000E+00 19 1 3 3 0 0 -1.105067427E+02 1.421821233E+02 -4.604244326E+02 4.947910210E+02 2.000000000E+01 0.00000E+00 9.000E+00 -19 1 3 3 0 0 1.364040084E+02 -8.606767262E+01 -1.601797817E+02 2.281912799E+02 2.000000000E+01 0.00000E+00 9.000E+00 21 1 1 2 501 502 1.176247515E+01 -6.794116046E+01 -6.893515132E+02 6.927913581E+02 7.629394531E-06 0.00000E+00 9.000E+00 21 1 1 2 511 501 -3.765974083E+01 1.182670980E+01 -2.003197011E+01 4.426518915E+01 2.384185791E-07 0.00000E+00 9.000E+00 #rwgt 1 27 4.458279237580892E-007 54217137 18503663 0 7 10001 1.95542E-05 9.79019E+00 -1.00000E+00 2.03118E-01 -5 -1 0 0 0 502 0.000000000E+00 0.000000000E+00 1.320324351E+02 1.320324351E+02 0.000000000E+00 0.00000E+00 9.000E+00 21 -1 0 0 502 511 0.000000000E+00 0.000000000E+00 -1.437605840E+03 1.437605840E+03 0.000000000E+00 0.00000E+00 9.000E+00 23 2 1 2 0 0 1.190509490E+02 1.913476912E+01 -7.998704366E+01 2.469110107E+02 2.000696184E+02 0.00000E+00 9.000E+00 19 1 3 3 0 0 1.221357406E+02 3.435915059E+00 -1.368507279E+02 1.845455672E+02 2.000000000E+01 0.00000E+00 9.000E+00 -19 1 3 3 0 0 -3.084791616E+00 1.569885406E+01 5.686368424E+01 6.236544351E+01 2.000000000E+01 0.00000E+00 9.000E+00 -5 1 1 2 0 501 -1.171095870E+02 -2.873054508E+01 -2.632058127E+01 1.234215240E+02 0.000000000E+00 0.00000E+00 9.000E+00 21 1 1 2 501 511 -1.941361983E+00 9.595775956E+00 -1.199265780E+03 1.199305740E+03 2.157918644E-05 0.00000E+00 9.000E+00 #rwgt 1 1 1.310511802431645E-006 54217137 18504554 0 7 10001 1.40949E-05 1.71134E+02 -1.00000E+00 1.16189E-01 5 -1 0 0 501 0 0.000000000E+00 0.000000000E+00 1.193437829E+03 1.193437829E+03 0.000000000E+00 0.00000E+00 9.000E+00 2 -1 0 0 502 0 0.000000000E+00 0.000000000E+00 -1.059155188E+03 1.059155188E+03 0.000000000E+00 0.00000E+00 9.000E+00 23 2 1 2 0 0 3.649319228E+02 -2.616708000E+02 9.057325966E+02 1.292992199E+03 8.061205701E+02 0.00000E+00 9.000E+00 19 1 3 3 0 0 1.869818869E+02 -5.506289544E+02 5.998478490E+02 8.356864923E+02 2.000000000E+01 0.00000E+00 9.000E+00 -19 1 3 3 0 0 1.779500359E+02 2.889581544E+02 3.058847476E+02 4.573057064E+02 2.000000000E+01 0.00000E+00 9.000E+00 5 1 1 2 502 0 -3.801460611E+02 9.121474866E+01 -6.087516405E+02 7.234706061E+02 0.000000000E+00 0.00000E+00 9.000E+00 2 1 1 2 501 0 1.521413825E+01 1.704560514E+02 -1.626983151E+02 2.361302123E+02 0.000000000E+00 0.00000E+00 9.000E+00 #rwgt 1 30 8.916683405805559E-006 54217137 18513050 0 7 10001 2.01168E-05 2.43846E+01 -1.00000E+00 1.63610E-01 21 -1 0 0 501 511 0.000000000E+00 0.000000000E+00 4.817909493E+02 4.817909493E+02 0.000000000E+00 0.00000E+00 9.000E+00 21 -1 0 0 502 501 0.000000000E+00 0.000000000E+00 -2.073755117E+02 2.073755117E+02 0.000000000E+00 0.00000E+00 9.000E+00 23 2 1 2 0 0 5.775404542E+01 -8.357506263E+01 1.536440670E+02 2.868107193E+02 2.198489675E+02 0.00000E+00 9.000E+00 19 1 3 3 0 0 1.638091468E+01 -1.387525077E+02 1.616069443E+02 2.145632709E+02 2.000000000E+01 0.00000E+00 9.000E+00 -19 1 3 3 0 0 4.137313074E+01 5.517744509E+01 -7.962877241E+00 7.224744845E+01 2.000000000E+01 0.00000E+00 9.000E+00 5 1 1 2 502 0 -7.898850597E+01 9.556292377E+01 -1.127390907E+02 1.675755324E+02 0.000000000E+00 0.00000E+00 9.000E+00 -5 1 1 2 0 511 2.123446054E+01 -1.198786115E+01 2.335104613E+02 2.347802093E+02 0.000000000E+00 0.00000E+00 9.000E+00 #rwgt 1 30 6.080127828600106E-006 54217137 18515932 0 7 10001 1.93103E-05 9.12593E+01 -1.00000E+00 1.28102E-01 21 -1 0 0 501 511 0.000000000E+00 0.000000000E+00 3.082500010E+02 3.082500010E+02 0.000000000E+00 0.00000E+00 9.000E+00 -5 -1 0 0 0 502 0.000000000E+00 0.000000000E+00 -6.980161432E+02 6.980161432E+02 0.000000000E+00 0.00000E+00 9.000E+00 23 2 1 2 0 0 -2.243618221E+01 -7.413103914E+01 -6.098931790E+02 6.488592217E+02 2.074844732E+02 0.00000E+00 9.000E+00 19 1 3 3 0 0 -1.248250686E+00 -9.827786529E+01 -1.153010892E+02 1.528215891E+02 2.000000000E+01 0.00000E+00 9.000E+00 -19 1 3 3 0 0 -2.118793152E+01 2.414682615E+01 -4.945920898E+02 4.960376326E+02 2.000000000E+01 0.00000E+00 9.000E+00 21 1 1 2 501 502 8.023825240E+01 1.447510435E+02 2.072809853E+02 2.652479002E+02 1.618438983E-05 0.00000E+00 9.000E+00 -5 1 1 2 0 511 -5.780207019E+01 -7.062000432E+01 1.284605154E+01 9.215902218E+01 0.000000000E+00 0.00000E+00 9.000E+00 #rwgt 1 29 2.349376421846550E-006 54217137 18520911 0 #Random number generator exit values: 54217137 18522497 0
