It includes filters to remove spurious candidate fusions with artifacts, such as misalignment or random pairing of transcript fragments, and provides a ranked list of fusion-transcript candidates that can be further evaluated via experimental methods. FusionSeq also contains a module to identify exact sequences at breakpoint junctions.

MRF was developed to address privacy concerns associated with the potential for mRNA sequence reads to identify and genetically characterise specific individuals; it is a compact data summary format that enables anonymization of confidential sequence information, while maintaining the ability to conduct subsequent functional genomics studies. RSEQtools provides a suite of modules that convert to/from MRF data and perform common tasks such as calculating gene expression values, generating signal tracks of mapped reads, and segmenting that signal into actively transcribed regions.

This tool is based on a data mining approach combining noisy data from ChIP-chip experiments with known binding site patterns. BoCaTFBS uses boosted cascades of classifiers for optimum efficiency, in which components are alternating decision trees; it exploits interpositional correlations; and it explicitly integrates massive negative information from ChIP-chip experiments.

PeakSeq employs a two-pass strategy in which putative binding sites are first identified in order to compensate for genomic variation in the 'mappability' of sequences, before a second pass filters out sites not significantly enriched compared to the normalized control, computing precise enrichments and significances. Our scoring procedure enables us to optimize experimental design by estimating the depth of sequencing required for a desired level of coverage and demonstrating that more than two replicates provides only a marginal gain in information.

The pipeline first constructs a diploid personal genome sequence, then map RNA-seq and ChIP-seq functional genomic data onto this personal genome. Consequently, locations where there are differences in number of mapped reads between maternally- and paternally-derived sequences can be identified and these provide evidence for allele-specific events.

| + | |
| - | the Gerstein lab has been a pioneer in applying network analysis to generate knowledge form large-scale experiments.To this end, we have developed TopNet-like Yale Network Analyzer (tYNA) for managing, comparing and mining multiple networks, both directed and undirected. This tools focuses not on individual genes and proteins but on the relationships between them. For example, Identifying defective cliques, finding small network motifs (such as feed-forward loops), calculating global statistics (such as the clustering coefficient and eccentricity), and identifying hubs and bottlenecks. To apply semantic web technologies such as resource description framework (RDF), RDF site summary (RSS), relational-database-to-RDF mapping (D2RQ) to more efficiently query life sciences data and meta-data we built YeastHub. The network tools developed in the Gerstein lab provide new insights into existing data and make information easy to find.

| - | ===Introduction===
| + | |
| - | To extract knowledge about the three-dimensional dynamics of proteins and ultimately their function we have built the Database of Macromolecular Movements (MolMovDB). Initially published in 1998 the main functionality was to interpolate the movements of macromolecules between two known crystal structures. In 2005 a number of additions were made. These additions include a more accurate method for interpolating multi – chain macromolecules, and an updated interface. In 2008 a Normal mode hinge prediction modal was added so that users could detect hinges in uploaded structures. The MolMovDB and its subsequent additions have provided knowledge about the functioning of proteins and of the structure of potential new drugs.
