Oh, I see. The swimmer which is used to make the trajectories assumes a constant B-field from what I remember of that code, so that's most likely the issue. I'm not sure how hard that would be to fix or if it would have undesirable repercussions to change it (decrease in runtime performance for instance). It would require hacking the converter so that it uses a much smaller step size and periodically updates the B-field value from the current trajectory position. -----Original Message----- From: Graham, Mathew Thomas Sent: Monday, April 27, 2015 6:07 PM To: McCormick, Jeremy I.

It could probably be easily modified to instead display all MCParticle collections regardless of their name. At least, I think that's probably why this collection wouldn't be showing in the event display. I think the problem is that they are showing up but not being bent correctly by the field... > > -----Original Message----- > From: [log in to unmask] > [mailto:[log in to unmask]] On Behalf Of Sho Uemura > Sent: Monday, April 27, 2015 3:49 PM > To: Alessandra Filippi > Cc: hps-software > Subject: Re: svt detector with new geometry not visible in WIRED > > I confirm that the v0 tracker shows up in WIRED but the v1 tracker does not - I'm doing recon on data using HPS-EngRun2015-2mm-v0 and HPS-EngRun2015-2mm-v1. > > Truth tracks from MCParticles would be nice.
