Calculation of FTB scores. For each CDS and its upstream and downstream surrounding regions, the X (plus strand) and Y (minus strand) values were TBLASTN bit scores expressed as a percentage of the TBLASTN bit self-score: X or Y = (bit score/bit self-score) Ă— 100. The difference between X and Y and between Y and X were calculated to minimize the background noise that could be due to the low complexity of some DNA regions. The result is four FTB scores per CDS, two per surrounding region one of which has a value ≥ 0 and the other has the same value but ≤ 0.
