Predicted non-redundant 3' and 5'SS associated AE motifs and their overlapping known motifs. Predicted AE motifs IDs and motifs are listed in columns 1 and 2. The motifs are displayed graphically as logos in the order of the IDs in column 1. The Motif ID includes a label for whether it was discovered relative to the 5' or 3' splice site and a numeric identifier for the motif in parenthesis. For all the kmers that define each motif in Column 2, Column 3 lists the range of ratios of the occurrence of these kmers in alternative exons versus constitutive exons. See Additional file 1, Tables S2 and S3 for the list of all motifs, their kmers and their numeric identifier. RESCUE-ESE and known enhancers (column 4) are taken from the survey in .
