The AIM API allows users of commercial and open-source imaging workstations to collect, manage, and store structured information and to associate that information with imaging features in a platform-independent manner. It also enables researchers to collect case-report information in the context of radiology studies, and to integrate that data with images as the basis for analysis and computer-aided diagnosis (CAD).

BACOM is a statistically principled in-silico approach to accurately estimating genomic deletions and normal-tissue contamination in order to recover the true copy-number profile of cancer cells. The BACOM API is a cross-platform and open-source Java application that implements the whole pipeline of copy-number analysis of heterogeneous cancer tissues and other relevant processing steps. The developers also provide an R interface, bacomR, for running BACOM within the R environment, through which users can smoothly incorporate BACOM into their specific analyses.

BioMixer supports ontology and ontology mapping visualizations in collaborative settings. In particular, BioMixer supports social interaction around the visualization. A user can send an existing visualization workspace to collaborators via email, as well as initiate discussions by adding notes to the visualization. BioMixer is accessible using a web browser and does not require the download or installation of any software. The tool supports the publication of visualizations by providing interactive visualizations that can be easily inserted into external websites. BioMixer supports users with diverse backgrounds and preferences by presenting multiple coordinated views that aim to engage the audience from different viewpoints.

The caArray Importer extends the caArray Java API to provide programmatic access for the retrieval of imported array designs; creation, modification, and deletion of projects; uploading, validation, and importation of array data files; modification of file type; and file removal.

The goal of caRuby is to reduce barriers to adopting cancer Biomedical Informatics Grid (caBIG) tools. caRuby simplifies interaction with caBIG application services by presenting a JRuby caBIG façade that supports the following: migration from legacy systems; incremental updating from source applications; extraction from a caBIG database; utility administrative tasks; workflow data transformations; lightweight web services; and site-specific user interfaces. There is a current implementation for caTissue.

Copy-Number Modules is a collection of software modules developed by the Emory In Silico Research Center of Excellence (ISRCE) that defines a pipeline for calculating copy-number data for the REpository for Molecular BRAin Neoplasia DaTa (REMBRANDT) project. The data created by this pipeline have been used to perform a Genomic Identification of Significant Targets in Cancer (GISTIC) analysis to define significant copy-number alterations in the transcriptionally defined tumor subtypes identified by The Cancer Genome Atlas (TCGA). This pipeline operates on the raw Affymetrix 100K SNP CEL files and produces a list of altered regions for each sample.

DDN is an analytical tool for detecting and visualizing statistically significant topological changes in transcriptional networks representing two biological conditions. Developed under caBIG's In Silico Research Center of Excellence (ISRCE) Program, DDN enables differential network analysis and provides an alternative way for defining network biomarkers predictive of phenotypes. DDN also serves as a useful systems-biology tool for users across biomedical research communities to infer how genetic, epigenetic, or environmental variables affect biological networks and clinical phenotypes. Besides the standalone Java application, a Cytoscape plug-in, CytoDDN, has been developed to integrate network analysis and visualization.

Whole-genome association studies are generating unprecedented amounts of genotype data and require new and scalable computational approaches to address challenges involving storage, management, quality control, and genetic analysis. GLU is a framework and a software package that was designed around a set of novel conceptual approaches.

LabKey Server is open-source software that helps scientists organize, analyze, and share biomedical research data. It is a secure, web-based data-management platform that provides a flexible and scalable foundation for building applications customized to researchers' protocols, analysis tools, and data-sharing requirements.

A data model and a database, PAIS has been designed as part of Emory's In Silico Research Center of Excellence (ISRCE) project to address the data-management requirements of detailed characterization of micro-anatomic morphology through many interrelated analysis pipelines. The data model represents virtual slide-related image, annotation, markup, and feature information. This set of information includes a) metadata about images; b) context relating to specimens; c) human observations involving pathology classification and characteristics; d) algorithm- and human-described segmentations, features, and classifications; and e) a description of the computation being carried out as well as identification of input and output datasets.

PUG-SVM is an analytical tool for multiclass gene selection and classification. Developed under the In Silico Research Centers of Excellence (ISRCE) Program, PUG-SVM addresses the problem of imbalanced class separability, small sample size, and high gene space dimensionality where multiclass gene markers are defined by the union of one-versus-everyone phenotypic up-regulated genes, and used by a well-matched one-versus-rest support-vector machine. PUG-SVM provides a simpler yet more accurate strategy to identify statistically reproducible mechanistic marker genes for the characterization of heterogeneous diseases.

QI-Bench provides open-source informatics tooling to characterize the performance of quantitative medical imaging as needed to advance the field. These tools may be deployed internally within an organization or used for collaborative work across organizations. The data on which they work may be accessible only to identified individuals or more broadly in an open archive to suit the specific project purpose.

swBIG is a web service that lets users treat caBIG data services as Linked Data. swBIG is available as a prototype representational state transfer (RESTful) service that converts requests for resources from linked data URIs into caGrid service calls to requisite grid endpoints. This service uses a representation of the NCI Thesaurus converted into a simple knowledge organization (SKOS) representation using web ontology language (OWL) to SKOS. This representation provides the ability to reason over concepts as instances in property value sets as well as in conceptual models.
