Applying easyExon on a public colon cancer dataset. (A) The transcript cluster of ACTN1. The 19th exon is upregulated in the tumor part of colon cancer (the red line). This exon is targeted by probeset 3569830 which is significant in both MIDAS (labeled with an asterisk) and PAC (labeled with "PAC") tests. The fold change of this probeset between groups is greater than 1.5 (in red). (B) The transcript cluster of CALD1. The 3' end of the 6th exon is downregulated in the tumor part. This region is targeted by probesets 3025631, 3025632 and 3025635 (circled in red) and is identified by MIDAS (labeled in red).
