ToA information in Timepix4

[krixikraxi]

Hi @simonspa

okay, then all should be fine now, thanks again for looking into it!

I am already using an adjusted version of the ADTreeWriter (with branches adjusted to Tpx4 structure instead of Tpx3), but I just saw that I had still called the GlobalTime as an UInt_t instead of Double_t, that fixed the resolution issue

I have also tried to implement the track_id as was discussed in this thread

Get the track ids from primary mcparticles

Hello, I used the DepositionReader module to feed Geant4 energy depositions to Allpix2. I have provided the particle pdg_id, track_id and parent_id with create_mcparticles set to be true. Now I am analyzing the digitized output of Allpix. I want to know how I can get the track_id of the primary particles in the digitized output. I am trying to do something like this: but I see that all the particleTracks are nullptrs in this case. I also don’t see any getter to access the particle track_id …

because I wanted to check if my clustering algorithm is properly differentiating the tracks/particles.
I added the lines as shown in the thread/Gitlab links into the MCParticle class and incremented ClassDefOverride(MCParticle, 10); to ClassDefOverride(MCParticle, 11); (as there are now already 10), but when I try to call it the same way as the ParticleID I still get only zeros. Do you have an idea what could be the issue there?

auto particles = hit.getPrimaryMCParticles();
auto mcparticle = (particles.empty() ? nullptr : particles.front());
        data_.pdg_codes_ = (mcparticle != nullptr ? mcparticle->getParticleID() : 0);
        data_.track_ = (mcparticle != nullptr ? mcparticle->getParticleTrackID() : 0);

Here is the ADTreeWriter I currently use: CERNBox

Thanks and all the best,
