#' @title Cell Cycle
#' @description This function executes a ubuntu docker that associates to each cell a cell cycle stage
#' @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 folder where input data are located and where output will be written and matrix name "/bin/users/matrix.csv"
#' @param separator, separator used in count file, e.g. '\\t', ','
#' @param G1_a, starting point in time series for G1 phase
#' @param G1_b, ending point in time series for G1 phase
#' @param S_a, starting point in time series for S phase
#' @param S_b, ending point in time series for S phase
#' @param G2M_a, starting point in time series for G2M phase
#' @param G2M_b, ending point in time series for G2M phase
#' @param seed, important parameter for reproduce the same result with the same input
