@fgrosa I should have addressed everything for Lc. Other 3 prongs have to be adapted.

[mfaggin]

@fgrosa Lc, D+ and Ds should be fine.

[mfaggin]

Also D* should be fine.

@fgrosa now also Xic->pKpi is in place. If you agree, I open it for review

Hi @mfaggin, thanks a lot! There are still a few files to be modified:

• https://github.com/AliceO2Group/O2Physics/blob/master/PWGHF/Core/HfMlResponseDstarToD0Pi.h
• https://github.com/AliceO2Group/O2Physics/blob/master/PWGHF/Core/HfMlResponseXicToPKPi.h
• https://github.com/AliceO2Group/O2Physics/blob/master/PWGHF/D2H/TableProducer/dataCreatorCharmResoReduced.cxx

thanks a lot @fgrosa, by mistake I overlooked the change of getInputFeatures for the Ds and Xic, my bad. This should be fine now.

Instead, for the resonance candidate creator I do not understand what I shall change. In fact, I only see the explicit query of PID information for the bachelor track/V0, and not for the daughters of 2-prong, 3-prong, or D* candidates. What am I missing?

Hi @mfaggin, you are indeed right!
I recalled that we were adding the PID of the daughter particles also for the reso builders (because the data model is essentially in common with the B hadrons), but that's not the case indeed. No need to modify the dataCreatorCharmResoReduced.cxx

thanks for the confirmation @fgrosa . Then, in principle there should be everything.
