Hi MadTeam, For a process with `ICKKW=1` matching, the banner file loses several information when we do `launch` the process again with a same runname. This is reproduced in v2.4.0 (May 12 2016), with pythia-pgs + delphes3 (latest). For example, with ./bin/mg5_aMC, consider the workflow ``` generate p p > t t add process p p > t t j output tt launch (with laststep=delphes, run_card automatically has ickkw=1) launch --name=run_01 ``` In this case, after the first `launch`, `tt/Events/run_01/run_01_tag_1_banner.txt` is generated. This file at this point has all information: ``` $ tail run_01_tag_1_banner.txt add Branch ScalarHT/energy ScalarHT ScalarHT } # Number of Events : 10000 # Integrated weight (pb) : 1058.914901 # Matched Integrated weight (pb) : 541.1 ``` However, this file is modified during the second launch, i.e., `launch --name=run_01`. After the launch the tail is ``` DECAY 16 0.000000 # vt : 0.0 DECAY 21 0.000000 # g : 0.0 DECAY 22 0.000000 # a : 0.0 # Number of Events : 10000 # Integrated weight (pb) : 1060.552755 ``` which has lost Matched Cross section as well as delphes card etc. (Note that the banner for the second launch is generated as `run_01_tag_2_banner.txt`.) Also, if we run more, like ``` generate p p > t t add process p p > t t j output tt launch launch --name=run_01 launch --name=run_01 ... ``` only the first banner `run_01_tag_1_banner.txt` loses the Matched cross section etc., and tag_2, tag_3, ... have complete information. This behavior is probably due to `add_generation_info` in `bin/internal/banner.py`. So, I guess this can be a bug, but rather I have the following question: * Is this workflow (multiple launch with same runname) correct/expected workflow? * What are the concepts `run` and `tag` ? (I am a bit sorry that I may have read this question here before but I could not find it)
