BCBB creates applications prepared by NIAID researchers and collaborators to share with the broader research community.

Examples of Web applications include the following:

The following are examples of downloadable desktop applications:

Additionally, BCBB is developing a new Web application called Nexplorer.

Evolutionary and comparative analyses are important tools used for the annotation of genomes. These analyses are hampered by the diverse file formats used in computational evolutionary analysis and the inability of analysis tools to sync with one another. Visualization and data management applications that can overcome these limitations are valuable for NIAID researchers performing these analyses. Comparative Data Analysis Ontology (CDAO), a data model developed and supported by the phylogenetic community, represents all the sets of concepts in an evolutionary analysis and the relationships among those concepts. BCBB is developing a Web application, Nexplorer3, using a semantic Web framework for visually manipulating comparative data in CDAO format and extracting biologically significant results based on reasoning. In addition, the ontology-based framework allows representation of data in different formats and improves interoperability of applications.
