[SOLVED] Steps to create a movie with objects and cameras moved independently of each other in PyMOL

Steps to create a movie with objects and cameras moved independently of each other in PyMOL

I have compiled open-source PyMOL v2.2.0a0 under Linux OS.

Reading this webpage and seeing this video, I tried the "copy to object / new" command on selections, moving them indipendently with the mouse in "edit mode", saving the state of the scene after each edit, but I can't interpolate between them.

In other words, I still can not understand how to realize a video like the one shown in that webpage.

Thank you for your attention,

best regards

Solution

Found the solution in this page: object motions—keeping the camera still, but moving the objects around the scene.

There is a working example:

# setup PyMOL for movies
reinitialize set matrix_mode, 1
set movie_panel, 1
set scene_buttons, 1
set cache_frames, 1
config_mouse three_button_motions, 1

# download the complex and setup it up fetch 1te1, async=0
extract AA, c. A
extract BB, c. B
color marine, AA
color grey, BB
as surface, BB
as cartoon, AA

# intialize the movie
mset 1 x410

# orient the scene
set_view (\

# move the inhibitor off the screeen
translate [0,0,100], object=AA

# first movie scene
frame 1
wizard message, "Let's watch the binder float it, while the camera doesn't move."
mview store, object=AA
mview store, object=BB

# 2 second pause for the user to catch up frame 60
mview store, object=AA
mview store, object=BB

# slide the inhibitor in from over the camera. :-)
frame 300
translate [0,0,-100], object=AA
mview store, object=AA
mview interpolate, object=AA

# store & wait 2 seconds...
frame 360
mview store, object=AA
mview store, object=BB
mview reinterpolate, object=AA
mview reinterpolate, object=BB

# 'explode' apart
frame 380
translate [-70, 70, 70], object=AA
translate [70, -70, -70], object=BB
mview store, object=AA
mview store, object=BB
mview reinterpolate, object=AA
mview reinterpolate, object=BB

You can save it in a .pml file (eg script.pml), in the default PyMOL path, to be able to call it with the command @script.pml inside PyMOL.

Here my demo 🙂
