Dear List,

I'm new to microarray analysis and need to calculate gene signal from
samples. The tab-delimited file has been prepared and the signal for each
probe is calculated. My question is: 1) How to filter the probes those are
disqualified? 2) How to calculate the gene signal from probe signal? The
reflection from probes to genes are clear but I have no idea if I need to
simply sum up all the probes of a given gene or something else.

Thanks a lot and best wishes.
