VGSC: A Web-Based Vector Graph Toolkit of Genome Synteny and Collinearity

الملخص EN

Background.

In order to understand the colocalization of genetic loci amongst species, synteny and collinearity analysis is a frequent task in comparative genomics research.

However many analysis software packages are not effective in visualizing results.

Problems include lack of graphic visualization, simple representation, or inextensible format of outputs.

Moreover, higher throughput sequencing technology requires higher resolution image output.

Implementation.

To fill this gap, this paper publishes VGSC, the Vector Graph toolkit of genome Synteny and Collinearity, and its online service, to visualize the synteny and collinearity in the common graphical format, including both raster (JPEG, Bitmap, and PNG) and vector graphic (SVG, EPS, and PDF).

Result.

Users can upload sequence alignments from blast and collinearity relationship from the synteny analysis tools.

The website can generate the vector or raster graphical results automatically.

We also provide a java-based bytecode binary to enable the command-line execution.
