Hi,

I am analysing 'rgu34a' affy chips.
I was able to extract expression values using 'rma' and
store the expression values in
the 'txt' file. When, I tired to read the 'txt' file using read.table(),
I get NA values (for all chips. but in the txt file, i do see the expression
values) for probesets such as D37951UTR#1_at. I tried to use
check.names=FALSE and as.is=TRUE options but not able to solve the issue.

Any suggestions?

Thanks in advance.

regards,
sharon
