Hello,
In a script, I am forming a string to be used as cut
in TTree.Draw() command, and I notice that ROOT crashes
when the string gets too long, the crash output is
appended at the bottom. In some cases, the crash
happened only after running over some large number of events,
while it ran fine on a smaller sample.
Is there a limit on the size of the string that one can use
to define a cut?
I append the offending string as illustration, and I am pretty sure
the length is the problem, because it runs if I just remove parts of it.
Is there a way to go around this and still using tree->Draw()
and a string as a cut. I know I can make a class and a selector
for my tree and then cut directly on the variables without strings,
but I would be glad if I don’t have to convert all my running scripts.
Best,
Vuko
