Missing streamer infos?

[Zehvogel]

Looks like FCCAnalyses might not close the output files correctly? They are missing streamer infos needed to be viewed with jsroot.

see: root-project/jsroot#259

Hi @Zehvogel,

Thanks for reporting an issue :)

Even with using with TFile context almost everywhere (PR #298) I'm still not able to get the JSROOT load the branch. See screenshot of the JS console at the bottom.

Quickly looking at the RVec reference page I can't see Streamer method.

Can you check with your analysis/file?

I cannot reproduce this issue anymore, seems to work fine at the moment :)

nvm, just ran into it again :/
the file I used is https://github.com/Zehvogel/resolutions/blob/main/analysis_stage1.py
The first root file created by this has the correct streamer infos and every following file is missing them...
I will try to make a smaller reproducer but so far I was not successful
