Hi everyone, I'm new to yt and am using the latest version (3.0), with support for TIPSY output. I'm having issues creating temperature slices. The data I am using is a periodic box, not equal length in all dimensions. My script goes like this: pf = load(fn, parameter_file=paramfile) pf.field_list slc = SlicePlot(pf,'z','temperature',width=(1,'kpc'),center=[0,0,0]) When I try to create the slice, I receive the following error: In [9]: slc = SlicePlot(pf,'z','temperature',width=(1,'kpc'),center=[0,0,0]) yt : [INFO ] 2014-06-16 11:14:40,033 xlim = -0.500000 0.500000 yt : [INFO ] 2014-06-16 11:14:40,033 ylim = -0.500000 0.500000 yt : [INFO ] 2014-06-16 11:14:40,033 Making a fixed resolution buffer of (('gas', 'temperature')) 800 by 800 yt : [INFO ] 2014-06-16 11:14:40,076 Making a fixed resolution buffer of (('deposit', 'Gas_smoothed_temperature')) 800 by 800 yt : [INFO ] 2014-06-16 11:14:40,096 xlim = -0.500000 0.500000 yt : [INFO ] 2014-06-16 11:14:40,096 ylim = -0.500000 0.500000 yt : [INFO ] 2014-06-16 11:14:40,097 Making a fixed resolution buffer of (('gas', 'temperature')) 800 by 800 yt : [INFO ] 2014-06-16 11:14:40,117 Making a fixed resolution buffer of (('deposit', 'Gas_smoothed_temperature')) 800 by 800 yt : [INFO ] 2014-06-16 11:14:40,138 Making a fixed resolution buffer of (('gas', 'temperature')) 800 by 800 yt : [INFO ] 2014-06-16 11:14:40,159 Making a fixed resolution buffer of (('deposit', 'Gas_smoothed_temperature')) 800 by 800 yt : [INFO ] 2014-06-16 11:14:40,183 Making a fixed resolution buffer of (('all', 'temperature')) 800 by 800 --------------------------------------------------------------------------- error Traceback (most recent call last) <ipython-input-9-4dae35760081> in <module>() ----> 1 slc = SlicePlot(pf,'z','temperature',width=(1,'kpc'),center=[0,0,0]) /net/imp/3/home/woodfiaj/python/yt-3.0/yt/yt/visualization/plot_window.pyc in SlicePlot(pf, normal, fields, axis, *args, **kwargs) 1779 del kwargs['north_vector'] 1780 -> 1781 return AxisAlignedSlicePlot(pf, normal, fields, *args, **kwargs) /net/imp/3/home/woodfiaj/python/yt-3.0/yt/yt/visualization/plot_window.pyc in __init__(self, pf, axis, fields, center, width, axes_unit, origin, fontsize, field_parameters) 1006 if axes_unit is None: 1007 axes_unit = get_axes_unit(width, pf) -> 1008 self.set_axes_unit(axes_unit) 1009 1010 class ProjectionPlot(PWViewerMPL): /net/imp/3/home/woodfiaj/python/yt-3.0/yt/yt/visualization/plot_container.pyc in newfunc(*args, **kwargs) 53 rv = f(*args, **kwargs) 54 args[0]._plot_valid = False ---> 55 args[0]._setup_plots() 56 return rv 57 return newfunc /net/imp/3/home/woodfiaj/python/yt-3.0/yt/yt/visualization/plot_window.pyc in _setup_plots(self) 745 zlim = (None, None) 746 --> 747 image = self._frb[f] 748 749 if image.max() == image.min(): /net/imp/3/home/woodfiaj/python/yt-3.0/yt/yt/visualization/fixed_resolution.pyc in __getitem__(self, item) 123 buff = self.pf.coordinates.pixelize(self.data_source.axis, 124 self.data_source, item, bounds, self.buff_size, --> 125 int(self.antialias)) 126 # Need to add _period and self.periodic 127 # self._period, int(self.periodic) /net/imp/3/home/woodfiaj/python/yt-3.0/yt/yt/geometry/cartesian_coordinates.pyc in pixelize(self, dimension, data_source, field, bounds, size, antialias, periodic) 52 if dimension < 3: 53 return self._ortho_pixelize(data_source, field, bounds, size, ---> 54 antialias, dimension, periodic) 55 else: 56 return self._oblique_pixelize(data_source, field, bounds, size, /net/imp/3/home/woodfiaj/python/yt-3.0/yt/yt/geometry/cartesian_coordinates.pyc in _ortho_pixelize(self, data_source, field, bounds, size, antialias, dim, periodic) 69 data_source[field], size[0], size[1], 70 bounds, int(antialias), ---> 71 period, int(periodic)).transpose() 72 return buff 73 error: data is of incorrect type (wanted 1D float) I have no idea what could be causing this, any ideas on how to solve this error?
