Hi, I have a simple question on using biomaRt but I did not find a proper manual to follow. I have a list of probes with affy ids and I want to convert them into entrezgene id. Is there a manual or example I can follow? Thanks. -- Weiwei Shi, Ph.D Research Scientist GeneGO, Inc. "Did you always know?" "No, I did not. But I believed..." ---Matrix III
