Subcodon profile plot showing RPF and input reads aligned to
actinb1. Reads are colored based on the frame (1, 2 or 3) position relative to the transcript (Michel
et al,
2012). All putative ORFs (distal AUG-Stop) were also colored for each respective frame (blue, pink and green boxes). Note that most of the RPFs from the annotated ORF match the color of the box, consistent with a strong in-frame distribution of reads within individual transcripts.
