MPSS flower (Lu et al. 2005)

from "Elucidation of the small RNA component of the transcriptome" Lu et al., Science 2005: 1567-1569. Colours of 17 b.p. signatures are based on the score in Transcripts Per Quarter million (TPQ). Signatures with 0 TPQ are blue; score 1 to 500 TPQ use a colour gradient which runs from dark blue-green to light green. Scores greater than 500 TPQ are coloured red and the arrow is double size.
