dynamo.sim.state_space_sampler(ode, dim, seed_num=19491001, clip=True, min_val=0, max_val=4, N=10000)[source]

Sample N points from the dim dimension gene expression space while restricting the values to be between min_val and max_val. Velocity vector at the sampled points will be calculated according to ode function.

  • ode (Callable) – The ODE function that will be used to calculate the velocity vector at the sampled points.

  • dim (int) – The dimension of the gene expression space.

  • seed_num (int) – The seed number for the random number generator. Defaults to 19491001.

  • clip (bool) – Whether to clip data points that are negative. Defaults to True.

  • min_val (float) – The minimum value of the gene expression space. Defaults to 0.

  • max_val (float) – The maximum value of the gene expression space. Defaults to 4.

  • N (int) – The number of points to sample. Defaults to 10000.

Return type:

Tuple[ndarray, ndarray]


The sampled points from the gene expression space and the corresponding velocity vector.
