- scanpy.tl.sim(model, *, params_file=True, tmax=None, branching=None, nrRealizations=None, noiseObs=None, noiseDyn=None, step=None, seed=None, writedir=None)[source]#
Simulate dynamic gene expression data [Wittmann et al., 2009] [Wolf et al., 2018].
Sample from a stochastic differential equation model built from literature-curated boolean gene regulatory networks, as suggested by Wittmann et al. [2009]. The Scanpy implementation is due to Wolf et al. [2018].
