     These data are derived from Affymetrix annotation file
     huex10stv2na23hg18. XHYB field is mainly an indicator 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.

        1.  1 unique. All probes in the probe set perfectly match only
           one sequence in the putatively transcribed array design
           content. The vast majority of probe sets are unique.  

        2.  2 similar.   All the probes in the probe set perfectly
           match more than one sequence in  the putatively transcribed
           array design content.

        3.  3 mixed.The probes in the probe set either perfectly match
           or partially match more than one sequence  in the putatively
           transcribed array design content. 

     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.
