There is no way this conversion does not exist in some common utilities yet.

@vkucera I had a quick look in O2 and O2Physics and I didn't find any common utility. Similar functions are defined in a couple of other places (
andO2Physics/Common/Tools/PID/pidTPCModule.h
Line 142 in 9eebc16
Do you have a concrete common utility that could be used?

Thanks for the links. I expected this to already exist somewhere close to the declaration of the o2::track::PID::ID but it seems I was wrong.

@mtorresc15 You can have a look here https://root.cern/doc/v640/TPDGCode_8h.html for the PDG constant definitions.

This PR fixes the PID assignment passed to getTrackParCovFromKFP() in candidateCreatorXic0Omegac0.cxx.
KFParticle::GetPDG() returns a PDG code, while getTrackParCovFromKFP() expects an o2::track::PID enum. This PR adds a helper function to convert the PDG code to the corresponding PID enum before calling getTrackParCovFromKFP().
