Dear rooters, What's the limit of the max .hbook file size when we use h2root? (or limit of statistics?) Now in KLOE we are taking long runs data about (100nb-1) for each run. It happens that for some runs when the .hbook file >10MB the h2root is not able to convert the file to .root successfully. Some strange message like following: (HI1E. 2 1882077( ) SY/US/IO 0040/00000/0003 NL/NS/ND 0/ 0/ 60 N/U/O/@O 0/ 1882232/ 1882150/ 1882077 (HCO1. 1 1882150( ) SY/US/IO 0041/00000/31A3 NL/NS/ND 2/ 2/ 70 N/U/O/@O 1882077/ 1882232/ 1882231/ 1882150 (HID1. 7000 1882232( ) SY/US/IO 0041/00010/2D15 NL/NS/ND 1/ 1/ 21 N/U/O/@O 0/ 1995059/ 1995057/ 0 ** LINKS 1882150(HCO1 At the end the file .root might not be well closed. Because when I opened the .root file afterwords I got warning err message TFile:TFile> file probably not closed. trying to recover. TFile:Recover> successfully recovered 3 keys. Could you give me an explanation? I can see the histograms after the file opened. But I am not sure the file has been converted correctly. Thanks a lot. By the way, thanks to Brun. After I redefined Directory instead of TFile as you wrote, now every pieces works properly!:) Cheers Meiwen
