PiPa (link)

PiPa is a tool to setup and maintain a local database for information on protein-protein interactions and biological pathways. It manages downloads and integration from a couple of public databases, including Reactome, BioCyc, BioGRID, GAD, MINT, IntAct, InHo, HPRD, PID, OMIM, MIPS, and UniProt. PiPa is not an application running on integrated data, but a tool to quickly create your own, in-house integrated database.

2005 - 2013: Ali Baba (link)

Ali Baba is a software for extracting the most important information from all results of a PubMed search. Given a PubMed query, it collects all matching articles (using NCBI's eUtils), identifies all genes, diseases, drugs, species etc. plus their relationships to each each other in any of the articles, and displays these as a graph of interlinked biomedical concepts. Runs as a Java Web Start application.

Alibaba was developed and maintained between 2005 and 2013, but is no longer supported.

2007 - 2013: PETER (link)

PETER is a library for DNA similarity search and joins. It indexes a large set of long DNA strings in a prefix-tree and allows for similarity searching using Hamming or edit-distance. Furthermore, two PETER indexes can be compared efficiently to perform a similarity join. Can be used as standalone tool, as a C++ library in other software, or as an extension for Oracle, thus allowing fast similarity operations with SQL.

PETER was developed and maintained from 2007 to 2011. The software is still available for download, but no longer supported.

2009 - 2012: LymphomExplorer

The LymphomExplorer is a web-based solution for integrated data management and analysis within large biomedical projects. It is developed in the course of the TRR-54 and funded by the Deutsche Forschungsgemeinschaft. It stores various types of processed microarray data (human, mouse, Affymetrix, Exon Chips, Agilent, etc.) and provides easy-to-use methods for quality control, clustering, and functional analysis of selected datasets.

The OmixAnalyzer was developed in the DFG-funded Collaborative Research Project (Sonderforschungsbereich / Transregio) TRR-54: Growth and Survival, Plasticity and Cellular Interactivity of Lymphatic Malignancies

LyphomExplorer was developed and maintained between 2009 and 2012. Please see our new tool OmixAnalyzer.

2008 - 2011: BC-Viscon

The BC-VisCon website provides an intuitive and flexible tool for viewing and analyzing aggregations and comparisons of the annotations made by the gene mention tagging servers connected to the BioCreAtIve-MetaServer.

BC-Viscon was maintained between 2008 and 2011.

2006 - 2008: DARQ (link)

DARQ is a query engine for federated SPARQL queries. It provides transparent query access to multiple, distributed SPARQL endpoints as if querying a single RDF graph. DARQ enables the applications to see a single query interface, leaving the details of federation to the query engine.

DARQ was developed in the course of the Graduate School METRIK, funded by the Deutsche Forschungsgemeinschaft.
