find max of a dataset?

I'd like to find the maximum value of every dataset in an hdf5 file.

Has anyone done this, perhaps with Python or C++?

Thanks,
Dave

Should be trivial in python; personally I use the h5py module for such things. Write a python function that recursively returns all dataset names as a /full/path/to/dataset (I can dig it out if you don't figure out how to do it yourself, cc me in that case). Finally, read out the arrays in a loop and call array.max() on each, put the results in a list, and call max() on the list.

Right?

Paul.
