How accurately is ncRNA aligned within whole-genome multiple alignments?

BMC Bioinformatics

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).
