Hi Sushil,
I do not know which file in your google drive is the one you used to make the plot, but I found some potential problems in a similar script yt_frb_offaxis.py:
1. When you load the data, with data = dict(?), the key values should be ?velocity_x/y/z? instead of ?cutting_plane_velocity_x/y/z?, since the later can be derived from the velocity field you provided;
2. The data for stream plot should not be normalized;
Here I attached the script, and you should be able to produce the figure without problem.
Best wishes, -- Suoqing JI Ph.D Candidate Department of Physics University of California, Santa Barbara http://web.physics.ucsb.edu/~suoqing

Dear Suoqing JI:
I tried with both factor=1 and deleting the ::factor (yt_frb_offaxis.py) but the same issue still persist (L(1,0,0) N(0,1,1).png). The only difference being that without the "factor" it takes longer time to compute than for a "factor=20".
For same data if I use "slc.annoate_streamline" gives approximately proper results (UniformGridData_Slice_y_field_x_t000.png) but without the offaxis
Any suggestions.
Thanks in advance

Hello yt users,
I tried to use the LightRay class to generate a light ray for one of my gridded simulation snapshots. The simulation is from the FIRE project which used a heavily modified version of Gadget-3 called GIZMO written by Phil Hopkins. And the error I got is: ValueError: need more than 1 value to unpack.

Hi Fei Li,
Since you're primarily trying to use Trident's functionality which wraps around the LightRay class, you should probably direct questions of this nature to the Trident mailing list. I'll start a discussion there on this topic now and cc you.
