• OS version: e.g. SLC6
• Compiler version: e.g GCC 4.9
• DD4hep version: nightly build from GitHub master
• lcgeo version: nightly build from GitHub master
• Reproduced by: ILDConfig GitHub master
• Input: on GRID: /ilc/prod/ilc/mc-dbd/generated/1000-B1b_ws/6f/E1000-B1b_ws.Pvvxyyx.Gwhizard-1.95.eL.pR.I35867.001.stdhep

• anajob output slcio: MCParticle collection is there, but all other collections are empty

As far as I understand, this problem occurs only, if the incoming beam particles are in the generator file - then nothing gets simulated. Our 3 ttbar event test (using an older stdhep file w/o incoming particles works fine). My prime suspects for this problem would be #310 and #315 as they both deal with the treatment of the MCParticle collections and we have not observed this problem before. @MarkusFrankATcernch and @andresailer could you please have a look ?

Jakob is working on this input file. Jakob said, these empty collections have not been seen with ilcsoft release v01-19-05.

@andresailer do you run regular simulation tests for CLIC with newer stdhep or lcio input files ?

[andresailer]

We just started using whizard2 now to create samples for simulation. Other samples were produced with pythia6 or whizard 1.9.5
