为什么champ.runCombat不允许我使用“幻灯片”作为批处理名称来纠正批处理效果？

Question

我正在使用ChAMP管道分析甲基化数据。我正在尝试使用champ.runCombat来纠正批处理效果，但是我一直收到以下错误：

pre_matrix= [[[], [], [], []], [[], [], [], []], [[], [], [], []], [[], [], [], []]]
m=0, matrix[m]=[[0], [], [], []]
m=1, matrix[m]=[[1], [], [], []]
m=2, matrix[m]=[[2], [], [], []]
m=3, matrix[m]=[[3], [], [], []]
post_matrix= [[[0], [], [], []], [[1], [], [], []], [[2], [], [], []], [[3], [], [], []]]

    Error in champ.runCombat(beta = myNorm, pd = myLoad$pd, variablename = 
    "PCL",  : 
      slide factors is not valid to run Combat, please recheck your dataset.
