Why do you use Affymetrix probe IDs as the input for the correlation analysis rather than the AGI codes?
You’ve probably memorised the AGI codes of your favourite genes, so converting to Affymetrix probe IDs is likely to be a nuisance. However, some genes are represented on both the ATH1 and AtGenome arrays, with different probe IDs. Some genes are recognised by multiple probe sets on one array or the other. Therefore we provide tools to convert a single AGI code or multiple codes to probe IDs allowing you to select which IDs you wish to use in the correlation analysis tools. Furthermore, some genes are not represented by probe sets on either array; preliminary conversion of codes therefore allows you to note which genes are (or not) represented and to select the required probe IDs from the available options before you start the analysis. We don’t want you to get a “probe set not present” Error message when you’re hoping to receive results useful to your research. Code conversion tools: ID Exchanger and ID/Func.
