Hi Tim, Thanks, and I'll try to follow the discussions. Just to put a "fresh" perspective (feel free to disregard), I think the policy should be that *everything* that is reconstructed is a persistent object. Then, there is an issue of data tiers - i.e. what is the data content of the "full event", "reco" and "micro-DST". Those can be adjusted as we learn more about how we exercise the computing model, and what resources are actually available to us. -y On Mar 12, 2013, at 5:38 PM, Nelson, Timothy Knight wrote: > Hi Yuri, > > Great! There is a big focus now (in fact, a meeting going on as I write this) on how to make sure we are persisting all of the information we want in LCIO and not keeping lots of excess garbage. At the moment, I think the tracks and ECal clusters are all persisted and in usable shape, but we need to create "reconstructed particles" that link to tracks, vertexes (currently not kept in LCIO output), ECal clusters, and muon clusters (not done yet), so that the EDM is complete for doing analysis. You should keep in touch with the gang here (Jeremy, Matt, Sho, Omar, Pelle) to make sure the information you need to do your analysis gets added in a timely way. There will surely be discussion of this in software meetings, as well as future smaller meetings (as with today) when you can make your voice heard. > > Cheers, > Tim > > On Mar 12, 2013, at 2:29 PM, Yuri Gershtein <[log in to unmask]> wrote: > >> Hi Tim, >> >> yes, I've been able to open the LCIO files that Joey has generated in ROOT. >> Thanks!! >> >> -y >> >> On Mar 12, 2013, at 2:21 AM, Nelson, Timothy Knight wrote: >> >>> Hi Yuri, >>> >>> Have you guys had a shot at this yet?
