SRR, = glob_wildcards("output.gtf/"+"{srr}.gtf")
#SRR = ["ERR188401","ERR204916"]
#rule all:
#    input:
#        expand("output.gtf/"+"{srr}.gtf",srr=SRR),

rule gtflist:
    input:
        gtffiles = expand("output.gtf/"+"{srr}.gtf",srr=SRR)
    output:
        output_txt = "MergedList.txt"
    run:
        with open(output.output_txt,'w') as f:
            for gtf in input.gtffiles:
                print(gtf,file=f)

第一行SRR后面有一个逗号

最开始没写这个逗号，一直遇到报错
