metID问题---识别的周期

Question

metID是在代谢组学领域进行代谢物鉴定的一揽子产品。内部数据库构建完成后，运行代码：

result <- metIdentify(ms1.data = "ms1.peak.table.csv", ##csv format
                       ms2.data = "QC1_MSMS_NCE25.mgf",##only msp and mgf and mz(X)ML are supported
                       ms1.ms2.match.mz.tol = 25,
                       ms1.ms2.match.rt.tol = 10,
                       ms1.match.ppm = 25,
                      ms2.match.tol = 0.4,
                       fraction.weight = 0.3,
                       dp.forward.weight = 0.6,
                       dp.reverse.weight = 0.1,
                       rt.match.tol = 60,
                       polarity = "positive", 
                       ce = "all",
                       column = "rp",
                       ms1.match.weight = 0.25,
                       rt.match.weight = 0.25,
                       ms2.match.weight = 0.5,
                       path = new.path,
                       total.score.tol = 0,
                       candidate.num = 3,
                       database = test.database,
                       threads = 3)

然后出错

  

match（x，table，nomatch = 0L）中的错误：         “匹配”需要向量参数
