RigiMOL is a feature only available in incentive PyMOL, not in open source built PyMOL.
The demo script is also pasted at here:
# get open and closed conformation of adenylate kinase
fetch 1ake 4ake, async=0
# make two state object
align 1ake and chain A, 4ake and chain A, cycles=0, object=aln
create rin, 1ake and aln, 1, 1
create rin, 4ake and aln, 1, 2
# morph from epymol
import rigimol rigimol.morph(“rin”, “rout”)
1. Steps, length of movie and resolution are tunable. I just show the movies using default (above) script.
2. Once the rout is made, movie can be save easily using “file -> save movie as”
3. I used MacPyMOL to made the two movies.
