I have an HDF5 data file that has some data sets stored as 1D arrays. I would like to somehow change the dimensions on the array to a 3D array. The total number of elements will remain the same, just the dimensions are different. Is there a way to do that in HDF5 quickly? Even a command line program with arguments would be great at this point.
I could probably write a short program to read in the data, then rewrite the data back out with the proper dimensions but I am trying to avoid writing that if I can.
Thanks for any help

Hi Mike,

Unfortunately not. In order to change dimensionality one has to modify object header information for the dataset. We do not have a public function or utility to do that. How often does this happen? And you know that data can be read into a buffer with different dimensionality, right?
