Programs

PAST

  • Institute for Genomics, Biocomputing & Biotechnology
  • USDA-ARS

In recent years, a method for interpreting genome-wide association study (GWAS) data using metabolic pathway analysis was developed and successfully used to find significant pathways and mechanisms explaining phenotypic traits of interest in plants. The scripts implementing this method were both difficult to use and slow to run, sometimes taking longer than 24 hours. PAST (Pathway Association Study Tool), a new implementation of this method, has been developed to address these concerns and implemented as a package for the R language. Two user-interfaces are provided---console and R Shiny application. PAST completed analyses in approximately half an hour to one hour and produced the same results as the previously developed method. Thus, to promote a powerful new pathway analysis methodology that interprets GWAS data to find biological mechanisms associated with traits of interest, we developed a more accessible, efficient, and user-friendly tool. PAST is available on GitHub, Bioconductor, and at MaizeGDB.

Keanu

  • Institute for Genomics, Biocomputing & Biotechnology
  • US Army ERDC

One of the main challenges when analyzing complex metagenomics data is the fact that large amounts of information need to be presented in a comprehensive and easy-to-navigate way. In the process of analyzing FASTQ sequencing data, visualizing which organisms are present in the data can be useful, especially with metagenomics data or data suspected to be contaminated. Keanu, a tool for exploring sequence content, helps a user to understand the presence and abundance of organisms in a sample by analyzing alignments against a database that contains taxonomy data and displaying them in an interactive web page. The content of a sample can be presented either as a collapsible tree or as a bilevel partition graph. Keanu is freely available at GitHub.

Quack

  • Institute for Genomics, Biocomputing & Biotechnology

The quality of data generated by high-throughput DNA sequencing tools must be rapidly assessed in order to determine how useful the data may be in making biological discoveries; higher quality data leads to more confident results and conclusions. Due to the ever-increasing size of data sets and the importance of rapid quality assessment, tools that analyze sequencing data should quickly produce easily interpretable graphics. Quack addresses these issues by generating information-dense visualizations from FASTQ files at a speed far surpassing other publicly available quality assurance tools in a manner independent of sequencing technology. Quack is freely available at GitHub.
