老师好，在做agilent单色芯片背景校正时，到Array5时报错，删掉array5的文件后，其他芯片全正常。

> BgCorrect=backgroundCorrect(EListRaw,method = "normexp",normexp.method = "rma",offset = 50)

Array 1 corrected

Array 2 corrected

Array 3 corrected

Array 4 corrected

Array 5Error in if (alpha <= 0) stop("alpha must be positive") : 

  missing value where TRUE/FALSE needed

In addition: Warning message:
