SCENIC is a workflow based on three new R/bioconductor packages: (i) GENIE3, to identify potential TF targets based on coexpression; (ii) RcisTarget, to perform the TF-motif enrichment analysis and identify the direct targets (regulons); and (iii) AUCell, to score the activity of regulons (or other gene sets) on … See more GENIE3 (ref. 8) is a method for inferring gene regulatory networks from gene expression data. In brief, it trains random forest models predicting the expression of each gene in the data set and uses as input the expression … See more AUCell is a new method that allows researchers to identify cells with active gene regulatory networks in single-cell RNA-seq data. The input to AUCell is a gene set, and the output is the gene set 'activity' in each cell. … See more GRNBoost is based on the same concept as GENIE3: inferring regulators for each target gene purely from the gene expression matrix. However, GRNBoost does so using the … See more RcisTarget is a new R/Bioconductor implementation of the motif enrichment framework of i-cisTarget and iRegulon.

Batch balanced kNN alters the kNN procedure to identify each cell’s top neighbours in each batch separately instead of the entire cell pool with no accounting for batch. The nearest neighbours for each batch are then merged to create a final list of neighbours for the cell. " - Scenic tsne
