In aertslab/AUCell: AUCell: Analysis of 'gene set' activity in single-cell RNA-seq data (e.g. identify cells with specific gene signatures)

#' @title Get gene set name (excluding number of genes/regions after space)
#' @description Returns the gene set name (i.e. selects the given pattern)
#' @param aucMat AUC matrix
#' @param patterns patterns
#' @param startChr  Character to indicate the start (typically "^")
#' @param endChr Character at the end of the gene set name, i.e. space or "_" after a transcription factor name
#' @return Returns the gene set name (i.e. selects the given pattern)

#' @export
