A The data were analyzed by categorizing the splice events into seven types: exon skip (ES), alternative 5' donor (AD), alternative 3' acceptor (AA), retained intron (RI), mutually exclusive exons (ME), alternative first exon (AP) and alternative last exon (AT). The analysis of splice events was performed using the following filter criteria: Min Gene RPKM>2, |dPSI|>0.1, p-value≤0.02, Min Group Obs % >.85; RPKM-reads per kilobase of transcript per million aligned reads; and |dPSI|-absolute changes in percent splicing (dPSI, ∆Ψ). The events are presented in Fig 6 Source data file 1 as differential expression of splice events between ESRP1_Low and ESRP1_High cases.
