Hi Joyce,
>From my experience the reason for that problem is that the number of
skipped rows is not equal for all files. Check which of you input files
has different number of rows to skip. I think that one of the wrappers
in marrayTools solve that problem.

Hi Jean,
I read the same file with function read.marrayLayout and
read.marrayInfo, 
they all work, but not with read.marrayRaw.
I also check my file, there is no extra comma after the last colume,
I still got the error message as following:
[1] "Reading C:/Documents and 
Settings/jxgu/Desktop/cDNAraw/WorkingFile/cDNA196M2.txt"
Error in "colnames<-"(`*tmp*`, value = fnames) :
        length of dimnames[2] not equal to array extent
In addition: Warning message: 
number of items read is not a multiple of the number of columns 
Thanks
