Name Release Date Description Loregic 2015 Loregic is a computational method integrating gene expression and regulatory network data, to characterize the logical cooperativity of regulatory factors. Loregic uses all 16 possible two-input-one-output logic gates (e.g. AND or XOR) to describe triplets of two factors regulating a common target, and finds the gate that best matches each triplet’s observed gene expression pattern across many conditions. Using human ENCODE ChIP-Seq and TCGA RNA-Seq data, we are able to demonstrate how Loregic characterizes complex circuits involving both proximally and distally regulating transcription factors (TFs) and also miRNAs.
Name Release Date Description AlleleDB 2016 AlleleDB is an online resource for storing and visualizing allele-specific binding (ASB) and gene expression (ASE). Using variants from the 1000-Genomes Project and RNA-seq and ChIP-seq data from related projects, this resource serves as a repository for the catalog of ASB and ASE variants, associated genomic elements and personal genomes used in the study. AlleleDB also interfaces with the UCSC browser for visualization of results. AlleleSeq 2011 AlleleSeq is a computational pipeline that is used to study allele-specific expression (ASE) and allele specific binding (ASB). The pipeline first constructs a diploid personal genome sequence, then maps RNA-seq and ChIP-seq functional genomic data onto this personal genome. Consequently, locations in which there are differences in number of mapped reads between maternally- and paternally-derived sequences can be identified, thereby providing evidence for allele-specific events.
Name Release Date Description MUSIC
MUSIC is an algorithm for identification of enriched regions at multiple scales in the read depth signals from ChIP-Seq experiments.
2009 A tool for calling peaks corresponding to transcription factor binding sites from ChIP-Seq data scored against a matched control such as input DNA. PeakSeq employs a two-pass strategy in which putative binding sites are first identified in order to compensate for genomic variation in the 'mappability' of sequences, before a second pass filters out sites not significantly enriched compared to the normalized control, computing precise enrichments and significances.
Name Release Date Description FunSeq
- & -
These tools can be used to automatically score and annotate the disease-causing potential of SNVs, particularly those which are non-coding. FunSeq can detect recurrent annotation elements in non-coding regions when running with multiple personal genomes. FunSeq2 is an extension of FunSeq that provides a means of prioritizing somatic variants from cancer whole genome sequencing. LARVA
2015 LARVA is a computational framework designed to facilitate the study of noncoding variants. It addresses issues that have made it difficult to derive an accurate model of the background mutation rates of noncoding elements in cancer genomes. LARVA integrates a comprehensive set of noncoding functional elements, modeling their mutation count with a beta-binomial distribution to handle overdispersion. Moreover, LARVA uses regional genomic features (such as replication timing) to better estimate local mutation rates and mutational enrichments. VAT
2012 A computational framework to functionally annotate variants in personal genomes using a cloud-computing environment.

PARE 2007 Protein Abundance and mRNA Expression (PARE) is a tool for comparing protein abundance and mRNA expression data. In addition to globally comparing the quantities of protein and mRNA, PARE allows users to select subsets of proteins for focused study (based on functional categories and complexes). Furthermore, it highlights correlation outliers, which may warrant further investigation.
