Hi guys, I want to use the nparticles rather than the particles callback so that I only plot PARTICLE_TYPE_MUST_REFINE (4). I am trying (full script at end of email): p.modify["nparticles"](1.0,p_ size=4.0, col='g', ptype='4') I tried with and without ' around the 4 but both times I get: Traceback (most recent call last): File "Density_movie.py", line 29, in <module> p.modify["nparticles"](1.0,p_size=4.0, col='g', ptype='4') File "/scratch/YT-x86_64/lib/python2.5/site-packages/yt-1.6dev-py2.5-linux-x86_64.egg/yt/raven/PlotTypes.py", line 52, in __getitem__ raise KeyError(item) KeyError: 'nparticles' Any idea what I am doing wrong?

Elizabeth,
I want to use the nparticles rather than the particles callback so that I only plot PARTICLE_TYPE_MUST_REFINE (4). I am trying (full script at end of email):
p.modify["nparticles"](1.0,p_ size=4.0, col='g', ptype='4')
Have you added a new function to yt/raven/Callbacks.py that does what you want, and that you've named (_type_name = "nparticles") correctly? There is no function currently named that in trunk. _______________________________________________________ sskory@physics.ucsd.edu o__ Stephen Skory http://physics.ucsd.edu/~sskory/ _.>/ _Graduate Student ________________________________(_)_\(_)_______________
ah, I had assumed it was there since it is on: http://yt.enzotools.org/doc/advanced/callbacks.html#available-callbacks !!! Thanks, I will look into it properly now, Libby 2010/1/4 Stephen Skory <stephenskory@yahoo.com>

So that everyone else is clear who is following along, what I think happened is Libby upgraded her trunk installation, which changed the name of the callback, but the online docs are slightly behind. The good news is that very soon the docs will be updated online to coincide with a point release of yt, and this disconnect should be temporary. _______________________________________________________ sskory@physics.ucsd.edu o__ Stephen Skory http://physics.ucsd.edu/~sskory/ _.>/ _Graduate Student ________________________________(_)_\(_)_______________
