Other Projects

A Genome Annotation Browser

Comparative analysis of annotations over genomics data can be a key to understand the functions of the genes and generate a new hypothesis. In this work, a data visualization approach is suggested that lets the domain experts visually compare the annotations in a detailed way, filter annotations by types and by their sources, and also allows them to explore the gene and see the DNA sequences and other information that could be relevant during comparisons. This approach has several advantages over other browsers which are visualizing similar data and it has a set of solutions that make the tool adaptable to a variety of tasks.
