Hi analysers, I think it's time we all agree on a standard dst and I can see it's on the agenda of the collaboration meeting, so maybe we should start the discussion. I would be nice to have a framework (that can be used for data from all collisions systems) ready for the meeting. As I see it we have to figure out a couple of things: - (the easy part) What should the DST contain? What information do we need from what detectors? I think the bdst is pretty close to what we want - maybe it needs a few modifications for the d+Au and p+p data. - How should we organize the data? I like the tree structure but I miss the run information. As it is now the run number is written down for every single event and information about spectrometer setting, trigger scale down, etc is not there. It would be nice to store it with the dst, but not in every event. Any ideas how to do this in a smart way in ROOT? Please comment (if you are interested in the future of BRAHMS analysis)...
