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 remains!

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.

Thanks a lot Elaine. The command line seems to work, but the gui does have nice features! This part is rather confusing

" If the number of frames and step increment are more than needed to reach the playRange bounds (default is the entire range: 0.0,1.0), the morph display will “bounce” back and forth."

So I wonder how to play the morph back and forth similar to the gui, and actually, how to only play the morph in a single direction, but from the gui. I also wonder if there's a quick record option similar to the gui, or do I have to use movie encode? It would also help if I can find the log of how all these gui commands are passed to chimera so I can customize it and use it for  the command line interface.

Cheers.

Hi Ahmad,
To morph between multiple maps (more than two) you have to use the command "vop morph" instead of the Morph Map tool.  For example,

vop morph #1,2,5

... but there are a lot of additional command-line options that you may want to use, see:

I hope this helps,
Elaine
