Hi Jay, There are two ways of using the mapGeneInfo function: command line and widget. I will discuss with John off-list what is the best way to get the widget component working for mapGeneInfo. But for the moment, if you like to creat the mapping, you can write a simple one line command: For example, in your mraw at Gnames@maInfo, if you have the following columns: "ProbeID", "ProbeName" where "ProbeID" have accession number. Than you can running the following line to enable a html link to the Source web site later on when using the function htmlPage. mapGeneInfo(ProbeID="SMDacc") Please e-mail me if you like more help setting the mapping up.
