These data are derived from Affymetrix annotation file raex10stv1na24rn4. XHYB field is mainly an indictor of weak assignment between a transcript cluster and the assigned mRNA, suggesting a potential crosshyb, CRSSHYB is a measure of the promiscuity of the probes within a probe set among transcribed sequences.
XHYB and CRSSHYB are used to remove probe sets characterized by multiple hybridization of exon probes Cross-hybridization potential of the probe set determined at the time of array design. This field is based on computational sequence alignment against all known and putatively transcribed array design content, which includes all potentially transcribed regions of the genome and other transcribed sequences that could not be mapped to the genome.
