Hey Britton, That was the issue, works exactly as intended now. I just have one other question about the override_bins part. I am currently making 3 different profiles, one for the gas, one for the darkmatter, and one for the stars. It seems like even with the same sphere object in yt, they use different bins. In order to make the bins between each profile the same, I have tried adding the dict asked for, but I am unsure of the proper formatting of this. I have tried a couple of different configurations, like the one posted below, but keep running into errors. I was unable to find anything in the documentation about such formatting for these types of dicts, do you know where such information is posted? Here is one dict I tried, as well as the error message. {(9, 26.321025738981803), (8, 23.39646732353938), (44, 128.6805702794666), (24, 70.18940197061814), (21, 61.41572672429087), (15, 43.86837623163633), (47, 137.45424552579385), (50, 146.22792077212114), (19, 55.566609893406024), (2, 5.849116830884845), (6, 17.547350492654534), (32, 93.58586929415752), (18, 52.642051477963605), (22, 64.3402851397333), (1, 2.9245584154424225), (7, 20.47190890809696), (28, 81.88763563238784), (36, 105.28410295592721), ('stars', 'particle_radius'), (29, 84.81219404783025), (37, 108.20866137136963), (41, 119.90689503313934), (43, 125.75601186402417), (35, 102.35954454048479), (38, 111.13321978681205), (25, 73.11396038606057), (49, 143.3033623566787), (20, 58.49116830884846), (0, 0.0), (45, 131.605128694909), (31, 90.6613108787151), (39, 114.05777820225448), (23, 67.26484355517572), (34, 99.43498612504237), (42, 122.83145344858174), (33, 96.51042770959995), (17, 49.717493062521186), (12, 35.09470098530907), (14, 40.94381781619392), (4, 11.69823366176969), (27, 78.96307721694541), (30, 87.73675246327267), (40, 116.98233661769692), (3, 8.773675246327267), (5, 14.622792077212114), (11, 32.17014256986665), (13, 38.019259400751494), (46, 134.52968711035143), (16, 46.79293464707876), (10, 29.24558415442423), (26, 76.03851880150299), (48, 140.37880394123627)} ---------------------------------------------------------------------------TypeError Traceback (most recent call last)<ipython-input-8-a7f92b976f9a> in <module> 27 28 rp_stars = yt.create_profile(sp, ('stars', 'particle_radius'), [('stars', 'particle_mass')], accumulation = True,---> 29 units = {('stars', 'particle_radius'): 'kpc', ('stars', 'particle_mass'): 'Msun'}, weight_field=None, override_bins=bins_dict) 30 31 rp_darkmatter = yt.create_profile(sp, ('darkmatter', 'particle_radius'), [('darkmatter', 'particle_mass')], accumulation = True, ~/anaconda3/lib/python3.7/site-packages/yt/data_objects/profiles.py in create_profile(data_source, bin_fields, fields, n_bins, extrema, logs, units, weight_field, accumulation, fractional, deposition, override_bins) 1058 extrema = sanitize_field_tuple_keys(extrema, data_source) 1059 logs = sanitize_field_tuple_keys(logs, data_source)-> 1060 override_bins = sanitize_field_tuple_keys(override_bins, data_source) 1061 1062 if any(is_pfield) and not all(is_pfield): ~/anaconda3/lib/python3.7/site-packages/yt/data_objects/profiles.py in sanitize_field_tuple_keys(input_dict, data_source) 960 dummy = {} 961 for item in input_dict:--> 962 dummy[data_source._determine_fields(item)[0]] = input_dict[item] 963 return dummy 964 else: TypeError: 'set' object is not subscriptable
