Selection of bipartite octamers
| Selection | Number of octamers |
|---|---|
| Total (0 ≤ n ≤ 12) | 65,536 × 13 |
| Peak space | 65,536 |
| Peak spacing: n ≠ 0, 1 & single peak | 41,158 |
| Dominance of peak space (P < E-5) | 9,022 |
| LDSS selection | |
| TATA or core | 903 |
| Solid type | 75 |
| Rest (REG & non-REG) | 8,044 |
Of the 13 spacing lengths, one with the highest appearance in the promoters was selected (Peak space), and octamers with spacing lengths of 0 or 1, and octamers with the two spacings of highest appearance (twin peaks) were removed. Distribution profiles were subjected to statistical analysis and octamers with a profile of P < E-5, as determined by the Chi-square test, were further selected. Selected octamers were subjected to LDSS analysis and TATA-, Core-, and Solid-type octamers were removed, providing a final 8,044 bipartite octamers.
