Error reweighting: 'ReweightInterface' object has no attribute 'combine_wgt'

[Andrea]

Dear experts,

I am generating the process p p > t t~ x0 with the model HC_NLO_X0_UFO-no_b_mass which in itself works fine. Now I wanted to perform a reweighting for different values of cosine alpha, using the reweighting syntax shown below. This crashes with the error mentioned in the subject, please find attached my logfile. I am running aMC@NLO version 2.6.2, and tried to run without any parton shower for now.

Any hint to what I am doing wrong would be highly appreciated :)

Cheers,
Andrea

Hi,

Thanks for the report, and sorry for the long delay (holliday period does not allow that much time for user support)
In attachment you will find the patch to make it work. This was develop for 2.6.4 (the dev version)
I'm not 100% sure if that error is the same on 2.6.2, in case try with 2.6.3.2

Cheers,

Olivier
