[Chimera-users] Chimera morph map multiple volumes

Hi Elaine,

I think I get what that means, however, how can I calculate the number of
frames needed for the entire playRange?

The other thing that I'm rather confused about is that when I run the
following command:

vop morph #1,0,2,6,0,1 playStep 0.1 hideOriginalMaps true interpolateColors
true frames 500 modelID #3

I get a morph that would correspond to 1->0 ->2 ->6 ->2 ->0 ->1!!! Why is
it showing 2 a second time?! I tried to restart chimera but the issue

P.s. is there a way to set the "volume viewer step" for the morph, so I
don't have to set it manually in the viewer and then supply the modelID
such as what's above?

Thank you so much.
