Dissertation/Thesis Abstract

A flexible comparative genomics framework for integrating heterogeneous sequence data
by Regier, Allison Ann Penner, Ph.D., University of Notre Dame, 2011, 102; 3496613
Abstract (Summary)

Genome sequencing technologies have revolutionized biology in the past two decades, yet data analysis has lagged behind data production. In this thesis, we present a framework for analyzing genomic data in more flexible ways than previous techniques. First, the framework allows researchers to design analyses that compare genomic samples directly instead of relying on reference-relative variant calls, as most current tools do. Second, we provide utilities to look at both assembly data and resequencing data in the same analysis, where previous tools were restricted to either looking at an assembly or at resequencing data. Finally, our framework allows researchers to flexibly incorporate alignments to arbitrarily many reference sequences into their analysis.

We describe FlexReseq, the software implementation of this framework. FlexReseq allows researchers to easily customize resequencing analyses using a simple configuration file to define positions of interest. We give results from applications of these tools such as genotyping strains of Plasmodium falciparum, finding diversity and divergence between strains of Anopheles gambiae, detecting inversions based on assembly and alignment information from A. gambiae, and exploring resequencing analysis using alignments to multiple reference sequences.
