mdo sets up a command to be executed upon entry into the specified frame of the movie. These commands are usually created by a PyMOL utility program (such as util.mrock). Command can actually contain several commands separated by semicolons ';'

USAGE

mdo frame : command

PYMOL API

 
cmd.mdo( int frame, string command )

EXAMPLE

// Creates a single frame movie involving a rotation about X and Y
load test.pdb
mset 1
mdo 1: turn x,5; turn y,5;
mplay
//Show waters within 4 Angstroms around the first residue from a 15 frame simulation trajectory
load structure.pdb
load_traj structure.dcd, structure, start=1, stop=15
mset 1 -15
for a in range(1,16): cmd.mdo(a,"hide sphere; select waters, (structure & i. 1 around 4) & resn HOH, state="+str(a)+"; show sphere, waters")

NOTES

The mset command must first be used to define the movie before "mdo" statements will have any effect. Redefinition of the movie clears any existing mdo statements.
