From: Improving the prediction of mRNA extremities in the parasitic protozoan Leishmania
Nucleotide and pyrimidine dinucleotide frequencies surrounding the mapped polyadenylation site of 218 expressed sequence tags from Leishmania infantum. Frequencies are averaged over an 11 nucleotide sliding window in order to smooth out the graph. Negative positions are 5' of the poly(A) site and positive positions are towards the downstream gene. Pyrimidine dinucleotides are considered to be any occurrence of consecutive C or T residues.
