#' @title Running circRNA prediction overlap
#' @description This function executes the docker container docker4circ to overlap circRNA predictions obtained from multiple tools
#'
#' @param group, a character string. Two options: \code{"sudo"} or \code{"docker"}, depending to which group the user belongs
#' @param scratch.folder, a character string indicating the scratch folder where docker container will be mounted
#' @param input.folder, string indicating the path of the folder containing the samples to overlap
#' @param output.folder, string indicating the path of the output folder
#' @param min_support, an integer representing the minimum number of algorithms detecting the circRNA.
#' @author Nicola Licheri
#'
#' @return The list of circRNAs detected in at least the user-defined number of algorithms
#' @examples
#'\dontrun{
