Though the errors in my original TProfile histograms are stored via Sumw2()…but when i extract those TProfile histograms for post processing my results and just rebin those it shows the warning “Sum of squares of weight already created”…So will whis warning affect my results…and also can anyone help me to remove this warning.
Attached is the screenshot of the warning i am getting while running the post processing macro…

Maybe @moneta or @couet knows what those warnings mean
