MadAnalysis not importing root files created with standalone Delphes, or delphes installed within madgraph.

[rmahbubani]

System Settings

Linux Mint 20
Python 3.8.10
gcc 9.3.0
MG5_aMC_v2_9_8 (and delphes and madanalysis installed from within using the install command)
MA5 1.10.9

Describe the bug

Madanalysis can no longer import root files created with delphes within the madgraph->madevent pipeline. More details can be found here: https://github.com/orgs/MadAnalysis/discussions/265. This is a definite showstopper for me, as I suspect it may be for others.

To Reproduce

./bin/ma5 --R
display main
Output: "File extension NOT readable in this session: .lhe .hep .hepmc .root .lhe.gz .hep.gz .hepmc.gz .root.gz .lhe.fifo .hep.fifo .hepmc.fifo .root.fifo .lhe.gz.fifo .hep.gz.fifo .hepmc.gz.fifo .root.gz.fifo"
Also when I try to input a root file it says file not found.

Hi Rakhi,

But MadAnalysis5 can import delphes root files that it created, can't it? Which is what the code is supposed to do from the very beginning.

Cheers,

Dear Benjamin,Thanks for your prompt response.  What you say is correct, but my point is that it used to work, and now it doesn't.  Running delphes within madgraph removes for me the convenience factor of having everything be generated within the same pipeline.  Also, I find it is less easy to control the delphes card when I run it within madanalysis since I'm having trouble learning vi :(((  Any idea what the issue is, and on which side the problem liies?Cheers,Rakhi On Sunday, December 1, 2024 at 11:55:49 PM GMT+1, Benjamin Fuks ***@***.***> wrote: Hi Rakhi, But MadAnalysis5 can import delphes root files that it created, can't it?

Hi Rakhi,

I have no idea why suddenly it does not work anymore, but this may be due to changes in MG5aMC and not in MA5. Therefore, I am afraid it is more for the MG5aMC developers than for us. If you want a quick fix, you can switch to the SFS detector simulator in MA5.

Cheers,

Benjamin
