Adding NumPy array to existing HDF5 file in PyTables?

Question

I have two sliced Numpy arrays stored in memory, say a and b, shape 1*480*640, how can I add them to an existing HDF5 file in PyTables? The existing HDF5 file has three arrays: n1,n2,n3, I want the new HDF5 file to have 5 arrays: n1,n2,n3,a,b . Thx!

What did you try? Did you try the function `createArray`? – Simon May 08 '12 at 04:36 — Simon, May 08 '12 at 04:36
How did you get the other arrays into the HDF5 file? – dtlussier May 08 '12 at 17:07 — dtlussier, May 08 '12 at 17:07

You can use createArray on the file object to do that (or if you need compression use createCArray/createEArray):

File.createArray('/','a', numpyArray)
