Hi Tim, The coordinates for the U133 Affymetrix probes can be found in the affyU133 table. The relevant fields are tName, tStart, and tEnd. qName is the name of the probes.
You can use the Table Browser to get all of this information. Click on "Tables" in the blue menu bar at the top of the page. Make these selections: clade: Mammal genome: Human assembly: Mar.2006 region: genome group: Expression track: Affy U133 table: affyU133 output format: selected fields from primary and related tables Click "get output". Select the following fields (and any others you are interested in getting the data for): tName, tStart, tEnd and qName. Click "get output". Please don't hesitate to contact the mail list if you require further assistance.
