Hello all, I am trying to generate a t t~ process with madgraph. I am working on a cluster - all goes well until the final step where it says Command "generate_events run_04" interrupted with error: Exception : program /home/users/s/senguptd/UniGe/Generation/MG5_aMC_v2_8_2/ttbar/Events/run_04/PY8_parallelization/split_0/run_PY8.sh 0 launch ends with non zero status: 1. Stop all computation Please report this bug on https://bugs.launchpad.net/mg5amcnlo More information is found in '/home/users/s/senguptd/UniGe/Generation/MG5_aMC_v2_8_2/ttbar/run_04_tag_1_debug.log'. Please attach this file to your report. Following is the process detail:
