your transpose fix DOES change things and it indeed may working now. Here is the first images I got for comparison. I am going to make a few more pictures to see if things are all good. Thanks very much,

I have actually seen this on one other system but I could never reproduce it. Could you tell me the version of yt you are using? If you run "yt instinfo" it should tell you. I haven't seen this bug for the last few months so I thought it was gone.
Additionally, can you try the following at the end of your script:
im=cam.snapshot('test1.png') write_bitmap(im, 'test2.png', transpose=False)
I think there may have been something wrong with the transposing of the image for a short time period a few months ago. I have very sporadic and unreliable internet at AAS but I'll try to respond as quickly as possible.
Sorry for the trouble,

I did some simple volume rendering with the following script:
volume2 = AMRKDTree(pf, fields=["Dark_Matter_Density"], no_ghost=False, tree_type="domain", le=c-0.5*WW, re=c+0.5*WW) cam = pf.h.camera(c, L, W, N, tf, volume=volume2, no_ghost=False, north_vector=L, steady_north=True) cam.snapshot(fn="%s_iso-DMdensity-%3.3d.png" % (filenameTHIS, j))
I got rather strange results in that the pictures look symmetric, which I am pretty sure can not be true. I attach the obtained plot. Note that I am using KD tree and using 32 cores.
Your help at your earliest convenience is appreciated. Best, Renyue
