How Does GCAT Work?
 Collects requests for DNA chips; currently 7 species available
 Obtains microarrays from academic suppliers
 Distributes chips to faculty teaching undergraduates
 Undergraduates conduct experiments
 Chips are sent to GCAT to scan (NSF-funded scanners)
 FTP data to students for analysis (< 24 hours)
 Students and faculty share data
