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

> 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.
