<div dir="ltr">HI Brian,<div><br></div><div>ds.all_data is a just a wrapper around ds.region that uses ds.domain_left_edge and ds.domain_right_edge. Looking at the source, I can see that it wasn't set up to accept any additional keyword arguments and pass them to region. This can be fixed easily in yt/data_objects/static_output.py (line 575), but in the mean time, you can just replace your ds.all_data call with:</div>
<div><font face="courier new, monospace">ds.region((ds.domain_right_edge + ds.domain_left_edge)/2., ds.domain_left_edge, ds.domain_right_edge)</font></div><div>and add your field_parameters keyword there.<span><font color="#888888"><br>
