#' @title Cells count table size
#' @description This function executes a ubuntu docker that counts row and colums of a counts table.
#' @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 separator, separator used in count file, e.g. '\\t', ','
#' @author Luca Alessandri, alessandri [dot] luca1991 [at] gmail [dot] com, University of Torino
#'
#' @return a file called dimensions.txt containing the number of row and columns of a cells counts table
