Can this be addressed with the function H5Tset_pad? The H5T documentation suggests that if you set the padding of the destination type to H5T_PAD_ZERO, the parts of the type not occupied by "meaningful" data should be set to zero. However, I've never tried this... Andrew _______________________________________________ Hdf-forum is for HDF software users discussion.
