Setting Noise in Heun Stochastic Integrator

[Borjan Milinkovic]

Hi all,

I'm trying to set the additive noise in a Heun stochastic integrator, but keep getting errors, my code is as follows:

integrator = integrators.HeunStochastic(dt=0.1, noise=noise.Additive(nsig=0.053))

And this is the error I recieve:

TraitTypeError: Attribute can't be set to an instance of <class 'int'> attribute tvb.simulator.noise.Additive.nsig = NArray(label=':math:`D`', dtype=float64, default=array([1.]), dim_names=(), ndim=None, required=True)

Is the code correct? I can't seem to find the solution. Any help is much appreciated.

Thanks, 

Boki

Hi,

The nsig attribute should be an array. Please try:

integrator = integrators.HeunStochastic(dt=0.1, noise=noise.Additive(nsig=numpy.array([0.053])))

Best,

Paula
