  1. *Sum of the ranks of the exonic 4-mers at the donor and acceptor splice site of the 34 lost introns. †A total of 10,000 iterations were generated. In each iteration, a total of 34 ranks were randomly generated according to the frequencies obtained from all the exonic 4-mers at the exon-intron boundaries of 33,011 FLS introns. Standard deviation is listed in the parenthesis. ‡The P value for the sums of the ranks of the donor and acceptor splice site.
