» a bioconductor package for annotating peaks identified from ChIP-seq, Chip-chip or any high-throuput experiments
(A collaboration with Dr. Lawson and Dr. Green)
Batch annotation of the peaks identified from either ChIP-seq or ChIP-chip experiments. The package includes functions to retrieve the sequences around the peak, obtain enriched Gene Ontology (GO) terms, find the nearest gene, exon, miRNA or custom features such as most conserved elements and other transcription factor binding sites supplied by users. This package leverages the biomaRt, IRanges, Biostrings, BSgenome, GO.db, multtest and stat packages

» a bioconductor package for analysis of high-throughput sequencing data processed by restriction enzyme digestion.
(A collaboration with Dr. Fazio)
The package includes functions to build restriction enzyme cut site (RECS) map, distribute mapped sequences on the map with five different approaches, find enriched/depleted RECSs for a sample, and identify differentially enriched/depleted RECSs between samples.

» Build Regulatory Network from ChIP-chip/ChIP-seq and Expression Data
(A collaboration with Dr. Heidi)
GeneNetworkBuilder (GNB) is a web appliation for discovering the transcriptional regulatory network for a given transcription factor (TF) of Caenorhabditis elegans, Homo sapiens and so on, using ChIP-chip (ChIP-seq) combined with gene expression profile from either RNA-seq or expression microarray experiments.
A R/Bioconductor package is also available.
» a bioconductor package to plot stacked logos for single or multiple DNA, RNA and amino acid sequence
(A collaboration with Dr. Brodsky and Dr. Wolfe)
motifStack is a package that is able to draw amino acid sequence as easy as to draw DNA/RNA sequence. motifStack provides the flexibility for users to select the font type and symbol colors. motifStack is designed for graphical representation of multiple motifs.
This package is involved in the pipeline of finding candidate binding sites for known transcription factors via sequence matching.
