  Subject: Question Loading Imagene Files into Limma


  I'm new at this.

  I used the following scripts to exclude data flagged as 1 or 2

   >myfun <- function(x) as.numeric ( x$Flag <= 0 )

  followed by

  > RG<-read.maimages(files,source="imagene",wt.fun=myfun)

  Then I get the following error messages

  Read header information
  Read 243c96Cy3flagschanged.txt 
  Read 243c96Cy5flagschanged.txt 
  Error in if (skip > 0) readLines(file, skip) : argument is of length zero
  In addition: Warning message:
  In readImaGeneHeader(fullname) : End of file encountered before End Header

  What do these error messages mean and how do I fix them.
