812 simulated expression datasets for differential co-expression analysis

Simulated expression data with knock-outs Description A dataset containing simulated expression dataset. Data is simulated using a dynamical systems model from a network sampled from the S. Cerevisiae regulatory network. The dataset is a list containing the results from the simulation, and other information generated subsequently. Format A named list with 14 elements: simitra numeric, indicating the iteration of the simulation (a total of 1000 were performed and 812 converged) scoresan S4 Matrix, containing vectorised inference scores of applying the methods implemented in the package. These are precomputed predictions inputmodelsa named list, storing the parameters used to sample the initial values of input genes. Proportions, means and variances of each gene is stored for each gene staticnetan igraph object, storing the initial regulatory network (150 node network) infnetan igraph object, representing the true differential network as determined using sensitivity analysis of the model netlayouta matrix (150 x 2), storing the (x, y) positions of nodes for laying out the graph infdensa numeric, network density of the true differential association network numinputa numeric, the number of input genes in the regulatory network. These are genes that have no regulators therefore need to be pre-defined numbimodala numeric, the number of input genes that are knocked-down therefore have a bimodal distribution numtfsa numeric, the number of genes in the network that regulate any other gene (are TFs) numcotargetsa numeric, the number of genes that are co-regulated, i.e. regulated by more than one TF dataan S4 Matrix, the expression data with samples along the columns and genes along the rows. Condition classification (KD vs WT) are stored as attributes of this object tripletsa data frame, consisting of gene triplets representing TF- Target associations conditioned on the gene knocked-down. Triplets are annotated for being in either the direct, influence and association networks sensmatan S4 Matrix, sensitivities of genes to TFs based on perturbation analysis of the simulation modelLoadThis dataset is in the form of an R RDS object.
