rotate can be used to rotate the atomic coordinates of a molecular object. Behavior differs depending on whether or not the object parameter is specified.

If object is None, then rotate rotates the atomic coordinates according to the axes and angle for the selection and state provided.

If object is set to an object name, then selection and state are ignored and instead of translating the atomic coordinates, the object matrix is modified. This option is intended for use in animations.

The "camera" option controls whether the camera or the model's axes are used to interpret the translation vector. To move the object relative to the camera set camera=1 (which is default), or to move the molecule relative to the model's geometry, set camera=0.

If this doesn't do what you want, consider Turn.

USAGE

rotate axis, angle [,selection [,state [,camera [,object [,origin]]]]]

ARGUMENTS

axis

x, y, z, or float vector: axis about which to rotate

angle

float: degrees of rotation

selection

string: atoms whose coordinates should be modified {default: all}

state

> 0: only the indicated state is modified
= 0: all states are modified
= -1: only the current state is modified {default}

camera

= 0 or 1: is the axis specific in camera coordinates? {default: 1}

object

string: object name (only if changing object matrix) {default: None}

origin

float vector: origin of rotation {default: None}

PYMOL API

cmd.rotate(list-or-string axis, angle=0, string selection = "all", int state = 0,
           int camera = 1, string object = None)

EXAMPLES

rotate x, 45, pept
rotate [1,1,1], 10, chain A
Electrostatic Map Caveat

If you have an electrostatic map and it's not rotating with the molecule as you expect it to, see the Turn command. Turn moves the camera and thus the protein and map will be changed.
