[Chimera-users] How to set volume view step size in "vop morph" command

Hi Zheng Liu,
Your command has “step 1” twice, but that should be OK… I believe it indicates using the full data in the calculation of the morph map.  
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#morph>

I'm not sure why the display uses step 8 of that map, or if it’s a bug, but here is one idea:
There is a volume option that by default, if a map is larger than a certain size, the display step size is automatically increased.  You could try turning off that behavior, for example with command:

volume #4 limitVoxelCount false

Details on that option
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/volume.html#sampling>

I hope this helps,
Elaine
