Documented in nClusterEvaluationSIMLR

#' @title Evaluation of the numbur of optimal clusters
#' @description This function analyze the data that came up from permutationClustering script.
#' @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 range1, First number of cluster that has to be analyzed
#' @param range2, Last number of cluster that has to be analyzed
#' @param separator, separator used in count file, e.g. '\\t', ','
#' @param logTen, 0 for raw count, 1 otherwise
#' @param nPerm, how many times number of cluster will be evaluated
#' @param percent, number of cells that has to be removed for bootstrap
#' @param rangeFile, name of the file that has for each row each number of cluster that has to be analyzed
