Table 6 Coding region boundary classifiers. Coding region boundary classifiers. Window sizes and positions are shown for the five coding region boundary classifiers used by CONTRAST. Coordinates are defined such that the boundary occurs between the adjacent positions -1 and 1 (that is, either position -1 is coding and position 1 is coding or the reverse is true), with coordinates increasing in the 5' to 3' direction. Each classifier's require consensus sequence is shown in the second column.
