Sorry for all the questions but I've never seen that "run" syntax before. What environment are you running? What IDE/OS/Python version etc? > trying... > header has been opened > succes! > Reading grid 20060511000000 at: Mon Oct 29 16:57:57 2007 > processing: 20060511000000 > > > Traceback (most recent call last): > File "Day_footprint.py", line 48, in ? > contribution=[contribution+grid[:,:,z:,k,0]/A for z in > range(len(H['outheigh > t']))] > ValueError: shape mismatch: objects cannot be broadcast to a single > shape Hmm, in this case the error isn't telli8ng us too much extra other than the line it doesn't like. But, putting this together with the code you posted earlier... --------------- for k in range(nr): contribution=N.zeros(shape(H['area'])) contribution=[contribution+grid[:,:,z:,k,0]/A for z in range(len(H['outheight']))] zplot[:,:,k]=zplot[:,:,k]+contribution; ------------- I will hazard a guess that N.zeros(...) is a different size to grid[:,:,z:,k,0]/A But since I have no idea what these look like - I assume its numPy or somesuch structure ? - I can only guess. Can you decompose the list comprehension and add some useful print statements to help debug it?
