Hi Peter, It is currently not possible to get the exon id and the affy external features as the information is on two separate attribute pages on the interface. I will add exon id to the Features attribute section for release 57 due out in a few weeks. For the moment you will need to do two searches. One to get the gene, transcript and exon ids from the Structures attribute section and another to get the gene, transcript and list of affy ids from the Features attribute section and compare the two result files. Apologies for any inconvenience caused. Regards Rhoda
