Constrained Elements (SiPhy, -omega & pi)
Summary: These files contain the 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.

Protein-coding Exons
Summary: A list of identified previous annotation and (Reference
annotation) novel conserved exons (Congo). Exons were identified
using a version of CONGO (previously developed for the Drosophila
genomes, see reference below) enhanced to handle mammalian exon
prediction. The enhancements include a semi-Markov feature to model
the short length distribution of mammalian exons, a synteny feature
for recognizing duplicated regions, and an alternative training
function to improve accuracy when performing an unbalanced prediction
task (only ~1.5% of the human genome is protein-coding).

Synonymous Constraint Elements
Summary: Identified coding regions with a very low synonymous substitution rate – indicating additional sequence constraints beyond the amino acid level. The Synonymous Constraint Elements (SCEs) are defined at three different resolutions (9-, 15-, and 30-codon). There is also a bedGraph track for the local estimate of the synonymous substitution rate (lambda_s). Also available at: http://compbio.mit.edu/SCE/

RNA Structures
Summary: The list of candidate predictions for structural RNA families. EvoFold structural predictions were based on a 31-way subset of the genome-wide 44-way multiZ alignment (consisting of 28 of the 29 eutherian mammals, together with opossum, chicken, and tetraodon as outgroups) and clustered into candidate families using the novel EvoFam algorithm. This data, as well as the complete set of structure predictions from the EvoFold screen can be downloaded in bulk or browsed through a UCSC Genome Mirror from the following web‐site:

In addition, individual families are listed and annotated in the following reference and its supplement.

Motif Instances
Summary: A list of instances of identified regulatory motifs. A motif catalog was built from TRANSFAC, Jaspar, and Protein Binding Microarrays using a method similar to that described in the reference below, with extensions for position frequency matricies. Motif instances were identified genome-wide using a FDR of 60%.

Chromatin Mark Data
Summary: ENCODE segmentation of hg18 into chromatin states for each of nine human cell types. States were learned using a Hidden Markov Model that computationally integrated ChIP-seq data into fifteen states associated with different types of functionality.

Human and Primate Accelerated Regions
Summary: Lists of human accelerated regions (HARs) and primate accelerated regions (PARs). Regions with accelerated substitution rates in either lineage were identified by first defining candidate elements using the phastCons program (not including the lineage of interest) and then scoring those elements for accelerated substitution rates in the subtree (human or primate) of interest.
