How to use the gseapy.gsea.SingleSampleGSEA function in gseapy

gs = GSEA(args.data, args.gmt, args.cls, args.outdir,
                  args.mins, args.maxs, args.n, args.weight,
                  args.type, args.method, args.ascending, args.threads,

                      args.figsize, args.format, args.graph, args.noplot, args.seed, args.verbose)
        pre.run()

    elif subcommand == "ssgsea":

                      top_term=args.term, no_plot=args.noplot, verbose=args.verbose)

and normalized enrichment score by obj.res2d.
             if permutation_num > 0, additional results contain::

                 | {es: enrichment score,
                 |  nes: normalized enrichment score,
                 |  p: P-value,
                 |  fdr: FDR,
                 |  size: gene set size,
                 |  matched_size: genes matched to the data,
                 |  genes: gene names from the data set
                 |  ledge_genes: leading edge genes, if permutation_num >0}
