This was not removed in #24876, or later in the master: please check and fix

Hi @perrotta I didn't understand exactly what is this problem. Could you please help me on this?. I didn't remove this line in 94X.

These lines are not there any more: therefore, someone did remove them.

It was done by this commit from @kpedro88 :
4c2621a#diff-496fcf98e9a0901abbe07acea8ebda40

The same commit on the master only removed one empty line:
cms-met@6503137#diff-496fcf98e9a0901abbe07acea8ebda40

Please find out together with Kevin what happened there, and provide a fix either in 94X or in the master (or both...)

These lines were removed deliberately, because this default value was not actually used (overridden later), and its presence was confusing. It should have been removed in the upstream PR also. Perhaps there was a mistake in the rebase.

This makes sense. Please provide a PR in the master with the same removal then, so that the backport will remain synchronized with it.

@eioannou please inform here as soon as the PR with the missing piece in the master is finally submitted, so that we can proceed with this backport

eioannou · 2018-11-05T16:36:55Z

Hi @perrotta should I make a new PR in the master removing those lines?

perrotta · 2018-11-05T16:54:24Z

As I already told you, either do so, or don't remove those lines in the backport: the backported code must be the same as the one merged in the master. According to what written earlier in this thread, I imagine that you should remove those lines in the master, in accordance to what was the original plan for this PR Emilios Ioannou <notifications@github.com> ha scritto:

Hi @perrotta, I have created a new PR #25129 for the master by removing the unnecessary lines in order to be consistent with this backport.

Faithful backport of MET EE noise mitigation in 2017 data #24876 and MET EE noise mitigation in 2017 data [remove unnecessary lines] #25129
A new filter is made available for users.
- If the parameters in PhysicsTools/PatUtils/python/tools/runMETCorrectionsAndUncertainties.py are kept at their default value the newly added filter is disabled, and therefore no effect can be propagated to the standard workflows (and no effect is seen in the results of the jenkins tests, in fact)
- As such the pull request can be merged without modifying the default behaviour, and it is therefore suitable for being backported

peruzzim · 2018-11-09T10:38:33Z

We need this ported to 10_2_X as well asap, @eioannou could you please open the PR already?

eioannou · 2018-11-09T14:21:04Z

@peruzzim the PR for 10_2_X is #25173
