Hi Mukesh,

I'm not sure I do fully understand -- the .yoda file contains 
histograms, i.e. the "per event" observables and their correlations have 
been lost. Otherwise it would be an ntuple file and would be *much* larger.

You can of course make transformations on the histograms, i.e. rescale, 
divide, integrate, ... but I think that's not what you're asking for?
