#' @title Running circRNA reformat script
#' @description This function executes the docker container docker4circ to reformat circRNA prediction file produced by a certain tool in a common format to further analysis.
#'
#' @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 which contains the input files to be reformatted
#' @param output.folder, string indicating the path to the reformatted circRNA prediction files
#' @param tool, string indicating the tool used to create the input files. Supported tools are: acfs, circexplorer, circexplorer2, circrnafinder, ciri, ciri2, dcc, findcirc2, knife, starchip, uroborus
#' @author Nicola Licheri
#'
#' @return A circRNA list reformatted in a tab-delimited file storing the circRNA genomic coordinates
