MG5_aMC vs amcfast and applgrid

Dear Meziani,

Did you use the special aMCfast analysis as given as example here: https://amcfast.hepforge.org/examples.html ?

best,
Rikkert

Dear Rikkert

 I didn't use it. I just use the analyse_td_pp_V.o present in fixed-ordered-analysis folder!

Meziani

Dear Rikkert

I relaunched the process and i used, this time, the given example file analyse_amcfast_td_pp_V.f.
It seems ok, but when i submit the generated root file for validation, ./aMCfast_validation /home/hep-ph/MG5_aMC_v2_6_1/amcfast_test/Events/run_04/

i get this error message:

3 observables found

The MADatNLO.top file contains scale variations

Dear Meziani,

thanks for reporting this problem.
I suspect that the crash might be due to the version of APPLgrid you are using (v1.4.97) that, according to the APPLgrid official website:

https://applgrid.hepforge.org

is not the current one.
Could you please try to downgrade APPLgrid to version 1.4.70 and let me know if you still get the same problem?
If so, it would be useful if you could link somewhere the grid you obtain so that I can look into it.

Best,
Valerio

Dear Valerio,

Thank you for your prompt answer!

well, in first time i tried to install the current version (v1.4.70) but i received this error message:
