MEDUSA and Gorgon

• Description: MEDUSA is an algorithm for learning predictive models of transcriptional gene regulation from gene expression and promoter sequence data. By using a statistical learning approach based on boosing, MEDUSA learns cis regulatory motifs, condition-specific regulators, and regulatory programs that predict the differential expression of target genes. The regulatory program is specified as an alternating decision tree (ADT). The Java implementation of MEDUSA will allow a number of visualizations of the regulatory program and other inferred regulatory information, implemented in the accompanying Gorgon tool, including hits of significant and condition-specific motifs along the promoter sequences of target genes and regulatory network figures viewable in Cytoscape.
• Data Input: Discretized (up/down/baseline) gene expression data in plain text format, promoter sequences in FASTA format, list of candidate transcriptional regulators and signal transducers in plain text format.
• Data Output: Regulatory program represented as a Java serialized object file readable by Gorgon and as a human readable XML file. Gorgon currently generates views of learned PSSMs, positional hits along promoter sequences, and views of the ADT as HTML files, and generates network figures as Cytoscape format files.

String kernel package

• Description:The string kernel package contains implementations for the mismatch and profile string kernels for use with support vector machine (SVM) classifiers for protein sequence classification. Both kernels compute similarity between protein sequences based on common occurrences of k-length subsequences ("k-mers") counted with substitutions. Kernel functions for protein sequence data enable the training of SVMs for a range of prediction problems, in particular protein structural class prediction and remote homology detection. A version of the Spider MATLAB machine learning package is also bundled with the code, which allows users to train SVMs and evaluate performance on test sets with the packaged software.
• Data Input: The mismatch kernel requires sequence data in FASTA format. The profile string kernel uses probabilistic profiles, such as those produced by PSI-BLAST, in place of the original sequences. The Spider SVM implementation requires both the kernel matrix and a label file of binary or multi-class labels for the training data; this data must be loaded into MATLAB variables before using Spider routing.
• Data Output:The kernel code produces a kernel matrix for the input data in tab-delimited text format. The Spider package trains SVMs and stores the learns classifier and results from applying the classifier on test data as MATLAB objects.
• Implementation Language: String kernel code is implemented in C. Spider is a set of object-oriented MATLAB routines.

MatrixREDUCE

• Description: Regulation of gene expression by a transcription factor requires physical interaction between the factor and the DNA, which can be described by astatistical mechanical model. Based on this model, the MatrixREDUCE algorithm uses genome-wide occupancy data for a transcription factor (e.g.ChIP-chip or mRNA expression data) and associated nucleotide sequences to discover the sequence-specific binding affinity of the transcription factor. The sequence specificity of the transcription factor's DNA-binding domain is modeled using a position-specific affinity matrix (PSAM), representing the change in the binding affinity (Kd) whenever a specific position within a reference binding sequence is mutated. The PSAM can be transformed into affinity logo for visualization using the utility program AffinityLogo, and a MatrixREDUCE run can be summarized in an easy-to-navigate webpage using HTMLSummary.
• Data Input: sequence file in FASTA format; and expression data file in tab-delimited text format.
• Data Output: PSAMs in numeric and graphical format, parameters of the fitted model, and an HTML summary page.
• Implementation Language: ANSI C, making use of Numerical Recipes routines.

T-profiler

• Description: T-profiler is a web-based tool that uses the t-test to score changes in the average activity of pre-defined groups of genes. The gene groups are defined based on Gene Ontology categorization, ChIP-chip experiments, upstream matches to a consensus transcription factor binding motif, and location on the same chromosome, respectively. If desired, an iterative procedure can be used to select a single, optimal representative from sets of overlapping gene groups. A jack-knife procedure is used to make calculations more robust against outliers. T-profiler makes it possible to interpret microarray data in a way that is both intuitive and statistically rigorous, without the need to combine experiments or choose parameters.
• Data Input: Currently, gene expression data from Saccharomyces cerevisiae and Candida albicans are supported.
• Data Output:
• Implementation Language: T-profiler is written in PHP, data is managed by a MYSQL database server

TranscriptionDetector

• Description:A tool for finding probes measuring significantly expressed loci in a genomic array experiment. Given expression data from some tiling array experiment, TranscriptionDetector decides the likelihood that a probe is detecting transcription from the locus in which it resides. Probabilities are assigned by making use of a background signal intensity distribution from a set of negative control probes. This tool is useful for the functional annotation of genomes as it allows for the discovery of novel transcriptional units independently of any genomic annotation.
• Data Input: Expression data (GEO or other platforms) and designation of which probes represent negative controls and which are data probes.
• Data Output: A text file with a list of probes corresponding to significantly expressed loci.

PhenoGO

• Description: PhenoGO adds phenotypic contextual information to existing associations between gene products and Gene Ontology (GO) terms as specified in GO Annotations (GOA). PhenoGO utilizes an existing Natural Language Processing (NLP) system, called BioMedLEE, an existing knowledge-based phenotype organizer system (PhenOS) in conjunction with MeSH indexing and established biomedical ontologies. The system also encodes the context to identifiers that are associated in different biomedical ontologies, including the UMLS, Cell Ontology, Mouse Anatomy, NCBI taxonomy, GO, and Mammalian Phenotype Ontology. In addition, PhenoGO was evaluated for coding of anatomical and cellular information and assigning the coded phenotypes to the correct GOA; results obtained show that PhenoGO has a precision of 91% and recall of 92%, demonstrating that the PhenoGO NLP system can accurately encode a large number of anatomical and cellular ontologies to GO annotations. The PhenoGO Database may be accessed at www.phenogo.org.
