An example of a track output of the Coverage analysis tool is shown in figure 21.54.
In the Biomedical Genomics Workbench resequencing is the overall category for applications comparing genetic variation of a sample to a reference sequence. This can be targeted resequencing of a single locus or whole genome sequencing. The overall workflow will typically involve read mapping, some sort of variant detection and interpretation of the variants.
This chapter describes the tools relevant for the resequencing workflows downstream from the actual read mapping.
First comes a description of a tool to perform quality check of targeted resequencing approaches, next we describe the three variant callers that come with the Biomedical Genomics Workbench for finding variants, followed by a section describing a coverage analysis tool used to identify fluctuations in coverage. Next, the format of the variants are described, and finally we go through the various tools for filtering, comparing and annotating variants.
