cut on DeltaR gives empty plot

Asked by Thomas Mathisen

Hi,

I'm trying to make a cut on my DeltaR plots in a parton-level. I write a part of the script in the following way

reject (j) DELTAR(j) < 0.4
plot DELTAR(j, j) [superimpose normalize2one]

But I get an empty plot no matter the number after < . Using no cut and the plot is full of stuff and events above 0.4 for that matter. What is weird is that I noticed that I can make the following cut

reject (j) DELTAR(j) > any_number

and get a nice cut at any_number with all the events after gone from the plot after that number.

What can the issue be? Why does reject (j) DELTAR(j) < any_number give an empty?

I'm using Madanalysis 5 v1.6.33 and Madgraph5_aMC@NLO 2.6.1.

Hope you can help.

/Thomas

Dear Thomas,

Can you please replace the file
  madanalysis/job/job_candidate_cut.py
with the attached one (in the case where you would not see any file, do you mind giving me your direct e-mail address?).

This should fix the bug (yes, this is a bug). I will commit the fix later.

Regards,

Benjamin
