[Pytables-users] writing pytables HDF files without python

[<ho...@gl...>]

Dear List,

We have a customer who wants to feed some of our programs taking
pytables HDF files from a Fortran program. We managed together to add
the required attributes to make shure pytables does not complain, but
we now have the problem that the Fortran 90 HDF routines write=20

            ATTRIBUTE "CLASS" {
               DATATYPE  H5T_STRING {
                     STRSIZE 5;
                     STRPAD H5T_STR_SPACEPAD;
                     CSET H5T_CSET_ASCII;
                     CTYPE H5T_C_S1;
                  }                =20
               DATASPACE  SCALAR =20
               DATA {
                  "Array"
               }=20
            }=20

into the generated HDF5 file which leads to the error message

...
  File =
"/usr/local/fitools/sandbox/linux/lib/python2.2/site-packages/tables/Grou=
p.py", line 125, in _g_openFile
    objgroup._g_openFile()
  File =
"/usr/local/fitools/sandbox/linux/lib/python2.2/site-packages/tables/Grou=
p.py", line 144, in _g_openFile
    raise RuntimeError, \
RuntimeError: Dataset object in file is unknown!
                      class ID: Array=AF#@o

It seems pytables reads too much data and so gets garbage after the
wanted string. Could there be a workaround either on the Fortran or
the pytables side.

Thanks for your help.

Kind regards
