Can't access some branches in MiniAOD #536

Closed yhs07128 closed 3 years ago

yhs07128 commented 3 years ago

I'm trying to read some branch

patMETs_slimmedMETs__PAT.obj.m_state.p4Polar_.Pt()

in MiniAOD, but uproot doesn't recognize it as a branch. If I do

event['patMETs_slimmedMETs__PAT.'].show()

it shows that the branch is not interpreted properly.

name | typename | interpretation
---------------------+--------------------------+------------------------------- patMETsslimmedMETs | edm::Wrapper<vector<pat: | AsGroup(<TBranchElement 'patMEpatMETs_slimmedME... | bool | AsDtype('bool') patMETs_slimmedME... | unknown | <UnknownInterpretation 'non...

There are multiple other branches with the same problem, but I'm not sure what's causing it.

Have you tried to read the file with uproot4? The new version is highly recommended and can easily be installed e.g. via pip install -U uproot.

Edit: just realised, it's uproot4 ;)

Actually I'm using uproot4. Should move the issue.
