Hi Brian, Looking at your code (and the current cookbook, which I have just now corrected and will rebuild the docs shortly) I believe the error is that it should be "weight_field" instead of "weight". For shorthand you don't need to supply the name of that argument, since in order it would be field, axis, weight: ph.add_projection("Temperature", 0, "Density") -Matt On Thu, Jul 22, 2010 at 10:43 AM, Brian Crosby <crosby.bd@gmail.com> wrote:

I'm trying to make a density weighted temperature projection on Kraken, and the weighting seems to be causing problems.  I get this error: Traceback (most recent call last):   File "./s_p_halos.py", line 23, in <module>     p = ph.add_projection("Temperature", 0, weight='Density') I'm puzzled because this exact same script works on my laptop, albeit with a much smaller data set.  Any ideas or suggestions would be greatly appreciated.
