Do you have an FTP site I can use?

The files range from 200 MB to over 1 GB.

Hi Peter,

Thank you for reporting the problem.

Could you send "bad.h5" to our help desk 
([email protected]<mailto:[email protected]>) so that
we can debug it?

Thanks

I'm trying to read some small slabs from a database and am getting invalid data

Opening the dataset in HDFView also shows incorrect values.

Trying it via the utilities, this command shows a similar failure:
h5dump -p -d "/Regions/Region1/Dataset" -s "175,0,0" -c "1,5,5" bad.h5

                      DATA {

                   }

Expanding the selection slight gives the correct data:
h5dump -p -d "/Regions/Region1/Dataset" -s "174,0,0" -c "2,5,5" bad.h5
Output:
HDF5 "bad.h5" {

   ALLOCATION_TIME {
      H5D_ALLOC_TIME_INCR
   }
   SUBSET {
      START ( 174, 0, 0 );
      STRIDE ( 1, 1, 1 );
      COUNT ( 2, 5, 5 );
      BLOCK ( 1, 1, 1 );
      DATA {
      (174,0,0): 5596.14, 5155, 7550.53, 8183.16, 6550.84,
      (174,1,0): 4673.81, 6764.91, 2571.05, 424.237, 3440.45,

      }
   }
}
}

Any idea on when I'm doing wrong or how to get the proper data?

Thanks,
