===== OrientGens =====

To get a current list of available orientation generators, please run **//e2help.py orientgens//** or for more detail, **//e2help.py orientgens -v 2//**.

A typical orientation generator looks like this:

  * //eman:delta=2.0:inc_mirror=0//

Note that the //perturb// option is on by default in the eman orientation generator, to reduce noise bias problems.

To get a RANDOM ORIENTATION %%__%%within a python script%%__%% with three random values (one for each EULER ANGLE, from positions on "the sphere"), do the following:

<code>
rand_orient = OrientGens.get("rand",{"n":1})    #Fetches the orientation generator

c1_sym = Symmetries.get("c1")                   #Generates the asymmetric unit from which you wish 
                                                #to generate a random orientation

rt = rand_orient.gen_orientations(c1_sym)[0]    #Generates a random orientation (a Transform object) 
                                                #using the generator and asymmetric unit specified
