Interactive data analysis in bisulphite DNA sequencing
Sequencing of bisulphite-modified DNA is a widely-used method for analysis of genomic methylation. Although straightforward in principle, a number of technical problems with sequencing and data analysis can impede progress.
CpGviewer aims to be a simple integrated tool for handling bisulphite sequencing projects. It can process plain text sequences or a variety of electropherogram formats, and allows interactive editing of the sequences, aligned to a reference sequence.
The primary and secondary CpGviewer editing windows look like this:
CpGviewer also offers the facility to design primers for bisulphite-treated templates and to output figures for publication, like this one:
