Editing Slerpy (section)

==Quick Start Tutorial==

If you haven't installed slerpy yet see [[#Installation|Installation]]

;Step 1: You probably want to start off in a nice clean working directory that just has the coordinate files you want to work with.
 
;Step 2: Read in your molecule(s) and create the various selections and representations that you want to include in the movie.
 
;Step 3: At the pymol prompt, type:

 import slerpy

;Step 4: Get your molecule in exactly the orientation and representation that you want to use for the beginning of your movie.
 
;Step 5: Type:

 sinsert

;Step 6: Using the mouse, move your molecule to the next orientation that you want to use. When you record the movie, the camera orientation will be interpolated between each consecutive pair of views. This can include changes in rotation, zooming, clipping etc.
 
:Loop back to Step 5. Continue this until you've got all your orientations stored.
 
:You can check how any set of transitions will look at any time by using the ''sshow'' command (see [[#Command Reference|Command Reference]] for details).
 
:You can adjust the rate of any transition using the ''ssetf'' command
 
;Step 7A: Add any actions to your views using the saction command. Any number of pymol commands can be strung together separated by semicolons. If, for example, you want to change your protein from a cartoon to a surface and add a ligand when you get to view 5 you would do the following (assuming you've defined the pymol selections prot and lig):
 
 sgo 5
 saction "hide cartoon, prot; show surface, prot; show sticks, lig"

;Step 7B (Alternative using scenes):

 sgo 5

:Now use the gui to create the representation you want and then:
 
 sscene

;Step 8: Save everything. Save your slerpy views and actions as well as a pse file of your current pymol session:

 swrite mymovie

This will create mymovie.key, which has all of the views, frame counts, actions etc. and mymovie.pse, the associated pymol session file.
 
;Step 9: Record the movie! Type:

 srecord

:You can then play the movie by typing the standard pymol command ''mplay'' or by clicking the play button in pymol.
 
;Step 10: If you save the pymol session again, the pse file will contain the movie which can then be shown immediately after startup without running slerpy.py. Note that pymol will warn you when you load a pse file that contains a movie.
 
;Step 11: If you want to, the movie can be exported using the mpng command (see the pymol [http://pymol.sourceforge.net/newman/ref/S1000comref.html#2_105 documentation]).  Also, see the useful article [[Making_Movies|Making Movies]].
