)

Arguments

countMatrix: countMatrix
gKO: gKO
qc_mtThreshold: A decimal value between 0 and 1. Defines the maximum ratio of mitochondrial reads (mithocondrial reads / library size) present in a cell to be included in the analysis. It's computed using the symbol genes starting with 'MT-' non-case sensitive.
qc_minLSize: An integer value. Defines the minimum library size required for a cell to be included in the analysis.
nc_lambda: A continuous value between 0 and 1. Defines the multiplicative value (1-lambda) to be applied over the weaker edge connecting two genes to maximize the adjacency matrix directionality.
nc_nNet: An integer value. The number of networks based on principal components regression to generate.
nc_nCells: An integer value. The number of cells to subsample each time to generate a network.
nc_nComp: An integer value. The number of principal components in PCA to generate the networks. Should be greater than 2 and lower than the total number of genes.
nc_scaleScores: A boolean value (TRUE/FALSE), if TRUE, the weights will be normalized such that the maximum absolute value is 1.
nc_symmetric: A boolean value (TRUE/FALSE), if TRUE, the weights matrix returned will be symmetric.
nc_q: A decimal value between 0 and 1. Defines the cut-off threshold of top q% relationships to be returned.
td_K: An integer value. Defines the number of rank-one tensors used to approximate the data using CANDECOMP/PARAFAC (CP) Tensor Decomposition.
td_maxIter: An integer value. Defines the maximum number of iterations if error stay above td_maxError.
td_maxError: A decimal value between 0 and 1. Defines the relative Frobenius norm error tolerance.
td_nDecimal: An integer value indicating the number of decimal places to be used.
ma_nDim: An integer value. Defines the number of dimensions of the low-dimensional feature space to be returned from the non-linear manifold alignment.
