Description

Summary: Lists of constrained elements.
For each 12-mer in the human genome a measure of constraint was scored using SiPhy (see reference below), both as a rate-based score (omega), and a measure that includes biased substitution patterns (pi). Those falling in annotated Ancestral Repeats were used as a background. An empirical cutoff score was set corresponding to 10% FDR, and all 12-mers above this score were considered significant. Overlapping significant 12-mers were clustered to yield larger elements.

Detail

There are four tracks in this set:

Constraint Elements pi lods score,
data: mean: 7.214417, min: 1.711200, max: 16.237301, std: 1.364699
Constraint Elements pi branch length score,
data: mean: 4.173642, min: -0.049714, max: 7.351400, std: 0.755658
Constraint Elements omega lods score,
data: mean: 7.667489, min: 1.676100, max: 16.680599, std: 1.378213
Constraint Elements omega branch length score,
data: mean: 4.255876, min: 0.301830, max: 7.376400, std: 0.731477
