Procedures applied to extract alternative exon candidates.

* The probeset likely indicate an exon, although multiple probesets may exist in an exon.
§ Signals of these probesets were plotted using the SId7 value (Figure 1). Note: In the fourth procedure, genes were retained if ≥50% of probesets in each gene had p≤0.05 in DABG. In the seventh procedure, according to the of probeset ID start position, upstream and downstream neighbor probesets were searched whose expression was detectable (DABG; p≤0.05). If ABS_ SId7 value of the neighboring probeset was ≥0.667, the neighbor was considered to have changed expression. A probeset was removed if both of its neighbors changed expression. If a probeset with only one neighbor, the probeset was removed if that neighbor changed expression. In the ninth procedure, in addition to comparing of the ABS_SI values, a probeset was retained when its SId7 and SId10 were a negative number and ≥1.35, respectively, or when its SId7 and SId10 are a positive number and ≤−1.35, respectively.
