"Track" error in MG5 pipeline

When I try to pass the MadGraph? output through Pythia+Delphes I get the following error:

" WARNING: cannot access branch 'Track', return NULL pointer

* Break * segmentation violation" .I've also attached the log.

I've been using the "FCC_basic" configuration card from the examples. The Delphes root file still contains events, so is it fine to do analyses with this file even though it produced this error?

Hi Ralph,

if you are happy with the root file, then ignore the error. I believe it is generated when it tries to convert the root file into an lhco file.
If you need the output in lhco format, you need to modify converters/root2lhco.cpp (which was originally designed to convert the output produced with the CMS and ATLAS cards).
