#' @title Reorganize Cluster
#' @description This function executes a ubuntu docker that merge two clusters
#' @param group, a character string. Two options: sudo or docker, depending to which group the user belongs
#' @param scratch.folder, a character string indicating the path of the scratch folder
#' @param file, a character string indicating the path of the file, with file name and extension included
#' @param nCluster, number of Cluster used in Kmeans to generate the clusters that you want to merge
#' @param A, first Cluster that has to be merged
#' @param B, second Cluster that has to be merged
#' @param separator, separator used in count file, e.g. '\\t', ','
#' @param sp, minimun number of percentage of cells that has to be in common between two permutation to be the same cluster.
