VisRseq is a framework for analysis of sequencing datasets that provides a computationally rich and accessible framework for integrative and interactive analyses without requiring programming expertise.

VisRseq framework provides an extendable collection of R apps, which offer a semi-auto generated and unified graphical user interface for computational packages in R and Bioconductor. To address the interactivity limitation inherent in R, several native apps are built into the framework that provide interactive exploration and brushing operations as well as an integrated genome browser. All apps can be chained together to create more powerful analysis workflows.

ALEA is a computational toolbox for allele-specific (AS) epigenomics analysis.

ALEA incorporates allelic variation data within existing resources, allowing for the identification of significant associations between epigenetic modifications and specific allelic variants in human and mouse cells. ALEA provides a customizable pipeline of command line tools for AS analysis of next-generation sequencing data (ChIP-seq, RNA-seq, etc.) that takes the raw sequencing data and produces separate allelic tracks ready to be viewed on genome browsers.

ChAsE (Chromatin Analysis and Exploration) is a cross platform desktop application that provides an interactive graphical interface for analysis of epigenomic data.

Chase allows users to interactively explore and analyze epigenomic data through an integrated clustering and heat map interface. Features include:

  • Exploration and visualization of the data using an interactive heat map and plot interface
  • Clustering the data automatically or manually by sorting and brushing the heat map
  • Exporting results for downstream analysis or as high quality images for publications

Spark is an interactive clustering and visualization tool.

Spark enables exploration of genome-wide data. It requires two inputs: (i) one or more data tracks, and (ii) a set of genome coordinates of interest. Sparks then extracts data from the input tracks at the specified regions of interest and clusters them. The resulting visualization uses the clusters as a high-level visual guide to the common data patterns in the input data and provides links to gene ontology analysis tools. It also supports the interactive inspection of individual regions within each cluster and connects them to existing genome browser displays, taking advantage of their wealth of annotation and functionality.

FindER is an analytical analysis tool to study epigenetic modifications and protein-DNA interactions from ChIP-Seq data.

Taking ChIP-Seq and Input DNA alignment files in the BAM format FindER generates regions of enrichment for a given significance (FDR). Currently alignments to human genome (hg19) and mouse reference (mm10), both paired-end and single-end, are supported. Some postprocessing options (e.g. combining closely positioned enriched regions and filtering on the enriched region size) are enabled with FindER. The data set saturation study option is also available with user configurable random partitioning of the sequenced reads.
