My name is Jason Vertrees and I'm an independent consultant working with DeLano Scientific to promote PyMOL. My previous work was in theoretical biophysics and machine learning to predict properties of proteins.

Also, I am the owner of the PyMOLWiki website. I started it to help the PyMOL community store and organize information regarding PyMOL.

If you are interested in Biophysical, Structural or Compuational Biology, check out BSCB@UTMB -- my old school.

Movie Notes

#
# Simple movie of independent motions
#

# This create an ala and a tyr.  It moves the ala indepdendent
# of the tyr. 
#
# Q: Why are the orientations off?  What is the equivalent
#    command to moving something with mouse_motions?

# reinit
reinitialize

set matrix_mode, 1
# turns on handy scene buttons
set scene_buttons, 1
# turns on the movie panel at the bottom of the sceen
set movie_panel, 1
# turns on a special mouse button panel
config_mouse three_button_motions

# start with an empty movie, scene 1 with 90 frames
mset 1 x90

# create an ala and tyr
frag ala
frag tyr
as spheres

# create our scene
translate [10, 0, 0], object=ala, camera=0
orient

# store the first frame
frame 1
mview store, object=ala

# goto the next frame
frame 45
translate [-20, 0, 0], object=ala, camera=0
orient

# store this frame
mview store, object=ala

#reinterpolate the scene
mview reinterpolate, object=ala


New motions

  • Enter alone will store+reinterpolate
  • Shift-Enter will just store & clears the reinterpolation
  • CTRL-Enter will store but not reinterpolate

New Scenes

  • setups the scenes first
  • then just goto the frame you want and hit enter and the current will be stored with it
  • or you can right-click on the movie_panel and store with scene
  • purge kills the matrix info for the object


New movie stuff

  • CTRL-LEFTCLK + DRAG RIGHT = add frame/states
  • CTRL-LEFTCLK + DRAG LEFT = erase frame/states
  • Rt clk on object
    • Shift+Middle = drag
    • shift+Left = rotate
