#' @title Annotating RSEM gene.results using ENSEMBL gtf and refGenome CRAN package
#' @description This function executes the docker container annotate.1, where refGenome is used to annotated gene.results and isoforms.results outputs from RSEM using ENSEMBL GTF annotation
#' @param group, a character string. Two options: \code{"sudo"} or \code{"docker"}, depending to which group the user belongs
#' @param rsem.folder, a character string indicating where gene.results file is located
#' @param genome.folder, a character string indicating the folder for the genome reference used for mapping and counting with \code{"rsemstar"} function. In this folder is present the GTF used for by RSEM
#' @author Raffaele Calogero
#' @return one file: annotated_genes.results, which is the annotated version of gene.results.
