[modeller_usage] problems with randomization

[Igor Dvortsov <>]

i've noticed something strange: let's try build serie of models in 
model_default.py-way, but with starting_model=1 and ending_model=10. we 
get 10 different models a1..a10. let's do it one more time with same 
script and we get another 10 models b1..b10. they are different between 
themself but coincide with previous serie, such as a1=b1..a10=b10.
i just don't understand it. each model is calculated by 
automodel.single_model(), inside it method 
self.randomize_initial_structure(atmsel) is called. so randomization 
takes place. how it can be that these randomizations led to coinciding 
results?

and the main question - how to make modeller give really random serie of 
models?


kind regards, Igor.
