To expand a little on what Matt said ealier, if you don't have the Dark_Matter_Density field, you should still be able to use the field particle_density_pyx. This uses a yt implementation of the cic_deposit routine to take the particle data and make a grid field out of it. Depending on the version of yt you're using, the field will either be called particle_density_pyx or just particle_density.

Hi Elizabeth,
Here's a script that does it; you can get this with "yt_lodgeit.py --download=1294".

Also, on re-reading your initial question, my initial suggestion of adding a profile using "ParticleRadius" and "ParticleMassMsun" *will* function, but it's not what you wanted.
Best,

Hi Christine and Matt,
Unfortunately, I don't have a Dark_Matter_Density field, just the
velocities, type, mass and index. (From looking directly at the contents of XXXX.cpu0000).
I'm afraid I also need my hand held more to use Matt's suggestion! Would it be possible to give me an example of how to call those functions? I tried to guess and failed miserably.
Thank you~
Elizabeth

Hi Elizabeth,
It should be. You can either do the CIC deposited DM density using the field "particle_density_pyx" ( http://yt.enzotools.org/doc/api/field_list.html#particle-density-pyx ) if you're on the 'stable' branch of the field "particle_density" if you're on the current development trunk. That will convert the DM to be like a baryon quantity.
If you'd rather do raw particle binning, there is also functionality for that by using the x field "ParticleRadius" ( http://yt.enzotools.org/doc/api/field_list.html#particleradius ) or one of its derivatives, and the y field "ParticleMassMsun".

Is this possible?
