Madspin, 'NonType' object has no attribute 'groups'

Asked by teddym

Dear MG5 authors:
     I'm generating events for a loop induced process, decay final states using MadSpin using none mode. However, in the MadSpin step, I receive following error:

>>>>>>>>>>>>>>>>>>>>>>>
INFO: Extracting the banner ...
INFO: process: g g > hh > l- l+ t t~ QCD =2
INFO: options: $$ a t t~ hl ha QCD^2=4 TZ^2==2
INFO: detected model: 2HDM_CPC_Type-I_NLO_cba_UFO-alignment. Loading...
Command "generate_events " interrupted with error:
AttributeError : 'NoneType' object has no attribute 'groups'
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
<<<<<<<<<<<<<<<<<<<<<<<<

Have no idea about this problem. Using the same model file, I can generate events without any problem for other processes.

Best
Ted

Do you have a debug file generated?
What that few information, I'm afraid that I will not be able to help.

Cheers,

Hi,

Do you have a space between QCD and =2 ?
If yes that is the likely issue since you should not have space between those two.
I'm actually surprise that the code does not crash earlier (maybe you have some warning related to that?)

Cheers,

Olivier

Hi Olivier:
     Yes, I accidentally add a space between QCD and =2. The code crash only at MadSpin step.
      After I remove the extra space, the code goes smoothly. Thanks!

     BTW, is the QCD=2 redundant with QCD^2=4 in my syntax?
     "g g > hh > l- l+ t t~ QCD=2 $$ a t t~ hl ha [noborn=QCD] QCD^2=4 TZ^2==2"

yes it is redundant.

Cheers,

Thanks Olivier Mattelaer, that solved my question.
