Comment 1 for bug 2038286

Dear Julien,

Thanks for the bug report. This is a known issue and will be fixed in version 3.5.2 of the code.

The fix is very simple, so if you don't want to wait for the next release you can apply it yourself. In the file

tttt_NLO_LHC_13TeV/SubProcesses/fks_singular.f

change the line 3409:

 30 format(i15,i2,6(1x,d14.8),6(1x,i2),1x,i8,1x,d18.12,1x,d18.12)

into:

 30 format(i15,1x,i2,6(1x,d14.8),6(1x,i2),1x,i8,1x,d18.12,1x,d18.12)

Note that launchpad might change the whitespace in these lines, so be careful when copying them into the Fortran source code. The change is adding the '1x,' after the 'format(i15,'. I hope this solves your problem. Note that you'll have to redo the event generation.

Best regards,
Rikkert
