I have two root files each with a matrix (not trees), I have to process those matrices and compare the histograms I created.
First I open the first file:
Then I do the projection for my specific selection:
Of course this create the new histogram in the current directory, I tried to decouple my new histogram from the current directory with:
and then I open the other file:
and do the projection of this one
I need to compare and analyze those two projections so I would like to access them at the same time and not going back and forth because I have many other matrices and projections to look, but even if I decouple the first one I can not see it (.ls) and plot it again. Since I have to do several operations with the histograms I could either find a way to save them in another root file but I’ve been trying to do several similar things for a while now and could not find a solution.
Thanks a lot for the help.
