Thus, for example, a predicted donor splice site with score > 100 is excellent; 50-100 is acceptable; 0-50 is weak; and below 0 is poor (probably not a real donor site). The PROBABILITY of a predicted exon is the estimated probability under GENSCAN's model of genomic sequence structure that the exon is correct. This probability depends in general on global as well as local sequence properties. This information can be used to assess the reliability of the predicted exon, e.g., it would be better to design PCR primers based on a predicted exon with probability > 0.95 than one with lower probability.
