RE: h2root : cannot determine size

Hello,

This message is only a warning. It tells you that the Exchange mode is used.
I attached your hbook file in PAW: it is empty Therefore the converted ROOT file is also empty.

Cheers
Olivier

Subject: [ROOT] h2root : cannot determine size

Hello,

i have a problem with h2root to transform a paw file to root format :

ccali60% h2root ggd_mu1.dat
 RZOPEN. Cannot determine record length - EXCHANGE mode is used.  Converting directory //example
TFile** ggd_mu1.root HBOOK file: ggd_mu1.dat converted to ROOT
 TFile* ggd_mu1.root HBOOK file: ggd_mu1.dat converted to ROOT
ccali60%

i put the file as attached, but to anticipate the case where the forum would remove the attached file, the file is also here : http://users.lal.in2p3.fr/escalier/ProblemRoot/

thank you very much

before to send the email, i looked on the web, especially : http://root.cern.ch/root/roottalk/roottalk00/2355.html but it didn't help me to fix the problem

in particular, i tried this :
ccali60% h2root ggd_mu1.dat ggd_mu1.root 1 1 8092 8000  RZIODO. Error at record = 2 LUN = 1006 IOSTAT = -1   RZOPEN. Error in the input file
 Cannot open fileHROPEN 0
 Error on hropen was 3
 Converting directory //example
TFile** ggd_mu1.root HBOOK file: ggd_mu1.dat converted to ROOT
 TFile* ggd_mu1.root HBOOK file: ggd_mu1.dat converted to ROOT
