Table 2.
Statistics of aligned segments in nonhuman species
| Count | Percent | Improvable | Percent | |
| Perfectly aligned elements | 4025 | 66.61% | - | - |
| Shifted elements | 707 | 11.70% | - | - |
| Chimeric alignments | 328 | 5.43% | 146 | 44.5% |
| Partial alignments | 310 | 5.10% | 79 | 25.5% |
| Possible alignment inversions | 4 | 0.06% | - | - |
| Possible losses of ncRNA | 669 | 11.10% | - | - |
| Aligned segments in nonhuman species | 6043 | 100% | - | - |
The count indicates the number of segments in other species aligned to (or near) a human ncRNA. The last two columns show the number of cases of alignments that can be improved by straightforward realignment (see text).
