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 returned.
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

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" {
DATASET "/Regions/Region1/Dataset" {

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