Candice Hansey, Michigan State University; Heather L. Merk, The Ohio State University
This sequence alignment webinar presented by Dr. Candice Hansey in October 2011 provides an overview of current tools used for sequence alignment. The webinar includes demonstrations of low-throughout alignment using the Basic Local Alignment Search Tool (BLAST) and also provides sample code and graphical output for whole genome alignment and next generation sequence alignment. Furthermore, the webinar includes a wealth of resources.
This one hour webinar has been divided into six videos, which are listed in order on this webpage. The seventh video is the full webinar. The powerpoint slides (in pdf format) are provided at the bottom of the page.
At the end of this webinar, you should be able to do the following:
- Obtain sequence from the National Center for Biotechnology Information (NCBI) website
- Format sequence for BLAST alignment
- Perform low-throughout BLAST searches
- Describe the steps required to perform whole genome sequence alignments using MUMmer
- Describe next generation sequence alignment resources, including FASTX and the tuxedo suite
- Locate resources to learn more about sequence alignment
- Part 1 – overview of the National Center for Biotechnology Information (NCBI) website
- Part 2 – Demonstrations using BLAST
- Part 3 – Using Exonerate for pairwise sequence alignment of ESTs and cDNA
- Part 4 – Performing whole genome alignments using MUMmer and short sequence alignments using Vmatch
- Part 5 – Next generation sequencing platforms, the fastq sequence file format, and sequence quality control using the FASTX-Toolkit
- Part 6 – High-throughput sequence alignment using the Tuxedo suite, including Bowtie and TopHat
- Part 7 – Additional alignment programs and resources, as well as the question and answer session

About the Presenter
Dr. Candice Hansey received her Bachelor of Science and Ph.D. degrees from the University of Wisconsin-Madison in the Genetics and Plant Breeding and Plant Genetics Programs respectively. Dr. Hansey is currently a postdoctoral researcher at Michigan State University where she is combining her background in plant breeding with bioinformatics to understand the genetic diversity in maize and potato and how that diversity can be utilized to improve commercial production.
