Thank you very much Elaine !

Specifically I try to visualize the full rotation cycle of ATP synthase using three structures: 5are, 5ari & 5fil
If I copy the second one as #5 and the third one as #6 and then executing:

morph #2,3,4,5,6 core 0.1 frames 75 wrap f rate linear

I have rotation in one side and then in the opposite side in one trajectory.

In my project, I would like to make a rotation in one direction but reproducing the full cycle in order that hte final snapshot was the same as the first one, I also tried something like:

morph #2,3,4,3,2 core 0.1 frames 75 wrap f rate linear

But the end frame was not like the first one .

Many thanks in advance

Enrico

The suggestion in the help page is to open the model twice (for example, two copies of same model open as both #2 and #5) and then put both numbers in the morph command.

"For a more complicated trajectory that visits the same conformation more than once, another approach is to open a given structure multiple times to give copies with different model numbers."

I hope this helps,
Elaine
