I noticed a quite odd behaviour in ROOT (5.13) when I use some TCut objects.
Everything goes well when I plot something from my ntuple using three TCut objects. But when I try to add another cut (as its own TCut as well as simply attaching >&&“cut-params”< to the other cuts) and plot it anew, ROOT returns
Error in <TBasket>: fNbytes = 6341, fKeylen = 77, fObjlen = 7920, noutot = 0, nout=0, nin=6264, nbuf=7920
file probably overwritten: stopping reporting error messages
Error in <TBranch>: File:...
- and sometimes with some unzip error -
Strangely enough when I plot the variables used fit parameters no error appears (as well when using the fit parameters “raw” in Draw() ). Also I can use problematic fourth TCut with any two the other three cuts and nothing happens but not with all three?!
Is there some limitation of the number of TCut cuts?
Cheers & Thanks for any idea,
