I have a CWN and one column is not being correctly translated into root with h2root, zero all the way. I use “h2root myntuple.hbk myntuple.root”.
My ROOT is 4.02/00, on Solaris.
But when I use the h2root coming with ROOT 4.00/08 on Linux, that column is translated correctly.
Then I checked further by generating the Class definition of this Ntuple and found all the UChar_t type columns, considered by ROOT, are not being correctly translated – all zero.
Are there special options for 4.02/00? Or this is a bug? Or I did something wrong?
This problem was fixed after 4.02. In your case specify teh 5th parameter as 0
******Error in invoking h2root
===> h2root file.hbook file.root [compress] [tolower] [lrecl] [bufsize] [optcwn]
if file.root is not given it will be = file.root
compress = 1 by default (use 0 for no compression)
tolower = 1 by default (use 0 to keep case of column names)
lrecl =0 by default (must be specified if >8092)
bufsize = 8000 by default (branch buffer size)
for cwn ntuple only: optcwn = 1 (default) 1-byte int -> char, 2-byte int -> short, (use 0 to keep 4-byte int)
