Use h2root (a program to convert an HBOOK file into a ROOT file)
This program is delivered with the ROOT distribution.
It is invoked via:
h2root hbook_file_name root_file_name compress tolower
if the second parameter root_file_name is missing the name will be
automatically generated from the hbook file name. Example:
h2root test.hbook
is identical to
h2root test.hbook test.root
- if compress is missing (or = 1)the ROOT file will be compressed
- if compress = 0 the ROOT file will not be compressed.
- if tolower is missing (or = 1) ntuple column names are converted to lower case
but the first character is converted to upper case. - if tolower = 2 same as tolower=1 except that the first character is also converted to lower case
