NAME

6       h2root - convert PAW HBOOK files to ROOT files
7

SYNOPSIS

9       h2root file.hbook file.root [compress] [tolower] [lrecl]
10

DESCRIPTION

12       h2root  you  can  use  to  convert your HBOOK/PAW histograms or ntuples
13       files into ROOT files. To use this program, you type the  shell  script
14       command:
15
16              h2root hbookfile rootfile
17
18       If  you  do  not specify the second parameter, a file name is automati‐
19       cally generated for you. If hbookfile is of the form  file.hbook,  then
20       the ROOT file will be called file.root.
21
22       This  program  converts HBOOK histograms into ROOT objects of the class
23       TH1F.  HBOOK profile histograms are converted into  ROOT  profile  his‐
24       tograms  (see  class TProfile).  HBOOK row-wise and column-wise ntuples
25       are automatically converted to ROOT Trees(see TTree).  Some HBOOK  col‐
26       umn-wise  ntuples may not be fully converted in case one of the columns
27       is an array with fix dimensions (eg. `var[6]')  or  is  a  multi-dimen‐
28       sional array.
29
30       HBOOK integer identifiers are converted into ROOT named objects by pre‐
31       fixing the integer identifier with the letter `h' if the identifier  is
32       a positive integer and by `h_' if it is a negative integer identifier.
33
34       In case of row-wise or column-wise ntuples, each column is converted to
35       a branch of a Tree.  Note that h2root is able to  convert  HBOOK  files
36       containing  several levels of sub-directories.  Once you have converted
37       your file, you can look at it and draw histograms  or  process  ntuples
38       using  the  ROOT  interactive module. You can also use the ROOT browser
39       (see TBrowser) to inspect this file.

41       The chapter How to read a Tree explains two ways to read a  Tree.  ROOT
42       includes  the  function  TTree::MakeCode  to automatically generate the
43       code for a skeleton analysis function. With
