This may also be a good option for you, Desika: http://yt-project.org/docs/dev-3.0/examining/low_level_inspection.html#exami... Cameron On Thu, May 22, 2014 at 10:38 AM, Nathan Goldbaum <nathan12343@gmail.com>wrote:

Hey Desika,

You're right, you need to use all_data:

import yt ds = yt.load("your_dataset") ad = ds.all_data() print ad["PartType0", "Coordinates"]

In general all yt data sources will print out the flattened data contained in the source when you query them like a dictionary using an unambiguous string field name or ('field_type', 'field name') tuple.

Hi yt,

I have a pretty simple question that I ought to know the answer to - how do I extract the actual values in the field_list or derived_field_list of a ds?

For example, I have a field: ('PartType0', 'Coordinates'),

but printing something like pf[('PartType0','Coordinates')] doesn't return the list of particle type 0 coordinates (or anything for that matter). Do I have to access this through a pf.all_data() command somehow?

Thanks -desika
