I agree with Matt that this looks hinky. I'll look at the code and make sure we trap this Exception
more gracefully.

Yeah, this is an failure mode I think we’ve seen before…it tries to calculate the path length of the tracks to the next layer in order to get the MS error.
The track parameters printed out here seem funny to me...
track params: 0.33654476569411973, 0.3715470696473806, -0.017612227732148794, 0.5016171795755748, 1289.7084037010472, 313.646930637243, -48.658595699839786,
I think these should be (in the lcsim tracking frame) (px, py, pz, ptot, x0, y0, z0)…if so these values for (x0,y0,z0) are crazy and this candidate should have been rejected before it gets here. You are using HPS-Full.lcsim as the tracking strategy, right?

1) I'm running montecarlo muon radiative and bethe-heitler trident events for 4.4 GeV beam energy, so that I can figure out how far out the threshold in z should be set for the muon vertexing
2) Stepan set me up to this.
3) I couldnt find existing events for this
4, 5) I have modified nothing: my command is /group/hps/hps_soft/slic/v00-02/slic/v03-01-04/build/bin/slic -P /group/hps/hps_soft/slic/v00-02/slic/v03-01-04/data/particle

5) I set EventMarkerDriver eventInterval to 1, and found that it was event #1778 that gets the error:

Hi, there.
Can we backup a minute here so I can get some info from you....
What are you trying to accomplish overall with this?
Who requested you to do this task?
Are there already existing simulated events at JLab that you can use for this?
What detector model exactly are you using? Have you modified at all any of the detector description files?
What version of SLIC are you using?
I'm not sure about that error. I've actually never seen it before...
Can you set "eventInterval" in EventMarkerDriver to "1" so that we can exactly which event is causing the problem?
Thanks.

Hi,
It could be that the recon steering configuration you are running expects the events to be run through the readout simulation first to simulate properly the timing and pile-up. This information is not present when you try to reconstruct directly the SLIC simulation output. (At least I think this is what that particular steering file expects as input.)
What is the result if instead you use the following steering file to reconstruct directly your single particle events?
steering-files/src/main/resources/org/hps/steering/recon/SimpleMCRecon.lcsim
If this file isn't present in your trunk then 'svn up' to get it, as I just added it.
I believe this should treat each event separately, and it should not depend on running the readout simulation first, so you should see reconstructed tracks.
This is essentially what I use in the "MCReconTest" in integration-tests to test reconstruction of SLIC output directly without running the trigger simulation first.
Your other option is running the readout simulation, either with the "NoPileup" steering file to treat each event separately, or inserting empty events so that your physics events will be properly spaced to create triggered events. (This is all covered both on the Confluence and in a bunch of previous emails to this list.)
But let's see if the simpler option I suggested works first before you try to run the readout simulation...
