hi,
My ROOT version infor is------>
QAInfo:You are using STAR_LEVEL : new, ROOT_LEVEL : 3.02.07
now,I am confronted with a strange problem as blow,
I drew some TProfiles and saved them in a root file.But every time I
open it using TFile,there would be a warning like this----->
WARNING, the StreamerInfo of class TProfile read from file
/direct/star+u/chengyh/centrality/analysis/result/MC_Tree/5/ptmean.root
has the same version (=3) as the active class
but a different checksum.
You should update the version to ClassDef(TProfile,4).
Do not try to write objects with the current class definition,
the files will not be readable.
When I list them and draw one TProfile,it works,but when I draw
one more TProfile under the same ROOT session,it fails and gives infor
as below--->
*** Break *** segmentation violation
Root > Function meanptvscent() busy flag cleared
and then stops.
I don't know why,but I guess it is because that the Nents of those
TProfile are very huge.Because I must draw these TProfiles one time,
but it always fails,how can I do then?
You can have a look my macro for drawing,I have inclosed it to you.

Best regards!
