Abstract: In the recent years, multiple types of high-throughput functional genomic data have become available that facilitate rapid functional annotation and pathway modeling in the sequenced genomes. Gene expression microarrays are the most commonly available source of such data, and increasing amount of other data, including protein-protein interactions, sequence, literature, and localization data are being generated. However, genomic data sacrifice specificity for scale compared to traditional experimental methods, yielding large quantities of relatively lower quality measurements.

This problem has generated much interest in bioinformatics in the past two years, as sophisticated computational methods are necessary for accurate functional interpretation of these large-scale datasets. This tutorial will present an overview of recently developed methods for integrated analysis of functional genomic data and outline current challenges in the field. The focus will be on the development and use of such methods for gene function prediction, understanding of protein regulation, and modeling of biological networks. This tutorial will be of interest to computational researchers interested in contributing to the field of data integration and analysis of heterogeneous data and to biologists with some computational background who are interested in using the methods on their experimental data and understanding their properties and limitations.

Abstract: Gene expression profiling has become a routine technique that can be useful to many applied life scientists in some stage of their research. The ease with which it is possible to generate thousands of gene profiles stands in no comparison to the difficult and often treacherous path of getting reliable conclusions or even interesting research directions from these data. The data are very noisy and many traditional computational techniques are not made to deal with large numbers of variables, i.e. genes. Further, appropriate statistical design is essential to make the best use of the limited number of arrays and samples that are in general available.

This course will cover three of the main aspects of microarray experiments: to design optimal or near-optimal microarray experiments; to perform simple but effective microarray data cleaning techniques; to perform effective hypothesis tests with accurate error rate control.

The R computing environment will be used to implement the different techniques discussed.

Abstract: RNA is a current focus of interest in molecular biology, due to post-transcriptional regulatory action of micro-RNA (miRNA) and small interfering RNA (siRNA), which allow geneticists to knock down protein translational products and better understand gene interactions. RNA seconday structure plays important roles in retranslation events such as incorporating selenocysteine using the UGA stop codon and in ribosomal frameshift  slippage events.

This tutorial surveys soem of the recent biology of RNA, obtained from ribosomal conformation analysis, and some important algorithms concerning secondary structure prediction and non-coding gene finders. We additionally include recent findings of the author concerning  the computation of the landscape of kinetic traps for RNA and the energy profile of random RNA.

Abstract: Hidden Markov models provide a probabilistic model of protein domain or family data. Databases of Hidden Markov Models can be extremely useful tools for the analysis of sequence data. While the Pfam database is unquestionably the most popular collection of HMM's in existence today, there are many other useful collections that are currently available, and some of them might be more suitable for a particular need. In addition, there are several versions of Pfam, and it is useful to know which version to use, and why.

In this tutorial we will examine the varieties of software methods that are currently available, for HMM searches and for related methods such as profile and PSSM algorithms. We will study many different HMM databases, with specific tips and pointers for optimizing results from each one. Finally, we will look at methods for the development of customized collections of HMMs, with the associated benefits and pitfalls.

Abstract: Projects such as genome sequencing and DNA microarray studies produce an ever-increasing amount of data and the area of computational biology now poses some of the biggest challenges in computer science and data mining such as data storage, visualization, and modeling. Statistical learning techniques are increasingly successfully applied for modeling, but they often require substantial algorithmic expertise: the conventional software packages do not naturally encompass variable-length sequences and general structures, thus, special-purpose algorithms must be implemented to solve the associated optimization problems.

This tutorial introduces a general framework, weighted finite-state transducers (WFSTs), that naturally matches a wealth of data in computational biology, together with a set of algorithms that efficiently allow for a series of operations on WFSTs, enabling biologists even with modest computer skills to successfully apply sophisticated alignment techniques and powerful kernel methods. It familiarizes the audience with WFSTs algorithms and techniques, their use and application to computational biology problems, and a software library (FSM Library) incorporating these algorithms and representations that is freely available for research and academic use.

Abstract: The objective of this tutorial is provide the student with the knowledge and tools necessary to perform semantic aggregation, integration and inference on biological pathway data. The Pathway Resource List at http://cbio.mskcc.org/prl contains over 150 biological pathway databases and is growing. However, to consolidate all the knowledge for a particular organism, one must extract the pathways from each database, transform those pathways into a standard data representation, and load the data into an integrated repository. This tutorial will provide the student with the ability to avoid common pitfalls and reduce the amount of work that must be performed in order to accomplish pathway integration, thus leading to more productive and efficient scientific research overall.

The intended audience consists of bioinformaticians, computational biologists and database developers. Participants should be familiar with intermediate-level programming concepts (APIs, UML, XML parsing, object models) and intermediate-level database concepts (SQL, data modeling, Entity-Relation diagrams, etc.) Topics covered include issues in biological knowledge representation, semantic web technologies, data cleaning, and fundamentals of the extract, transform and load (ETL) methodology, illustrated through real world examples.

Abstract: With CPU chip speeds peaking, simply upgrading the processor no longer offers the performance benefit that it did, leaving many of us facing a brick wall. This performance tutorial will teach you how to overcome this barrier and get more out of your applications using your /existing/ system(s). Basically, there are two approaches to address a performance bottleneck: 1) software - modify the code itself to parallelize and optimize it; 2) hardware - increase the efficiency of utilization through scheduled resource allocation. Both approaches will be covered in this tutorial through detailed case studies.

After a short introduction to application performance tuning, we will zoom in on parallelization. The OpenMP programming model will be introduced through relevant examples that will highlight how and when to apply its simple but powerful features. OpenMP is a widely available open standard (http://www.openmp.org).

Key DRM technologies (LSF, SGE, PBS) and how they differ, as well as key grid concepts including policy allocation, resource reservation, backfilling, accounting, reporting, and billing will be discussed. DBI (University of Delaware) will present several of their current problems in computational biology with solution instructions that attendees will be able to replicate and apply. Live demonstrations will be used throughout the tutorial to better illustrate how to execute the instructions that will be provided.

Abstract: Biomedical advances are increasingly stymied, not by a lack of experimental data, but by a lack of data that is available in computable form. Biological data must be readily accessible, comparable, and fully correlated, and it must be captured in a language that allows the formulation of coherent testable hypotheses if it is to efficiently provide relevant answers to scientific inquiries and thus enable discoveries. The bottleneck in research today, in other words, is the task of sifting through large data sets to decide what experiments should be done.

Ontological frameworks can provide a shared language for communicating biological information and thereby integrating biological knowledge and removing this data bottleneck. These rigorous semantic descriptions of the entities and relationships between these entities can then be used to formulate hypotheses about and navigate through the volumes of data. To this end there are an increasing number of groups developing ontologies in assorted biological domains. However, these efforts will only be beneficial and aid biological data integration if certain criteria are met. These prerequisites are that the ontologies are non-overlapping, that they are accepted and used by the community, and that they are well-principled.

Abstract: The evolutionary history of species is best represented by a phylogenetic tree and there exist many well-known methods for reconstructing such trees, in particular, from bio-molecular sequences. However, for some types of data, this may not be appropriate and approaches that generate phylogenetic networks may be more suitable. For example, hybridization between different plant species or recombination between closely related bacteria can lead to sequence data whose evolutionary history is best represented by a network.

There are two types of phylogenetic networks: ones that are intepretable as non-tree-like models of evolution, and ones that do not possess such an interpretation, but should rather be considered as visualizations of incompatibilities within a data set. Examples of the former are ancestral recombination graphs, hybridization networks and reticulation network, whereas examples of the latter are splits graphs, consensus networks and neighbor-nets. This tutorial will discuss both types.

We will first give a brief introduction to reticulate evolution and phylogenetic networks. Then, a number of important network reconstruction methods will be discussed. Finally, the application of some phylogenetic methods will be illustrated using typical data sets (haplotypes, plant hybrids, and whole genome data for a set of prokaryotes).

Abstract: Much knowledge about genes and proteins is reported in the vast amount of biomedical literature. The recent advancement of high-throughput biological techniques is accompanied by a steady and overwhelming increase in the number of related publications. Thus the ability to rapidly and effectively survey the literature forms a necessary step for both the design and the interpretation of any large-scale experiment, as well as for the timely curation of biomedical knowledge in public databases. Consequently, the past few years have seen a surge of interest in biomedical text mining. Several text-related disciplines are harnessed in such efforts, including natural language processing, information extraction, and information retrieval.

The objective of this tutorial is to provide a structured introduction to the biomedical text mining field, from both the biomedical-application and the text-mining perspectives. It will present general and biomedical-specific text mining methods, examine and analyze existing work in biomedical literature mining, and place it in the framework of the explicit text mining disciplines. The tutorial will especially emphasize critical assessment, validation and evaluation methods that are used in text mining and information retrieval, and survey recent evaluation initiatives.

Abstract: Diseases that individuals develop late in life have no direct influence on their reproduction. Variants of genes that contribute to the susceptibility, onset or severity of these diseases are therefore likely to be kept in the population. Together with environmental factors, combinations of such defects lead to polygenic diseases. Some common autoimmune dieases (e.g. Multiple Sclerosis, Rheumatoid Arthritis) but also heart diseases and obesity are examples. Genes in polygenic diseases need to be investigated in combination for their phenotypic effects. However, genetic studies in humans are extremely difficult. Animal models came to rescue with shorter generation times, common environments and directed breeding.

Strains are searched that differ in the susceptibility to a disease. Genetic markers determine differences in the genotype. Statistical association of markers with differences in the trait of the disease among the individuals of the F2 or later generations led to the concept of quantitative trait loci.

This presentation explains how to combine the genotyping and disease phenotypes with RNA expression levels. In this connexion, the RNA expression level of genes is interpreted as a trait of the disease. Equivalent analyses yield expression QTLs representing candidates for cis- and trans-controlling regions for gene expression. With genes interacting, the effect on the expression of genes may be changed by more than the sum of the individual loci (epistatic effects). The cross-comparison with information on molecular pathways, extracted from Medline abstracts or manually curated, yields explicit candidates for further evaluation.

The approach is discussed on the example of a murine model of Multiple Sclerosis.

Abstract: Computation is playing an ever increasing and vital role in biology creating demand for new machines. Vendors strive to meet demand with advanced computer architectures. In this tutorial, we will give an overview of IBM's Blue Gene system, both the hardware and software architecture. We will emphasize the key features that allow thousands of processors to work together on a user's problem. We will present the programming model used. We will explain ways to take advantage of the Blue Gene nodes and associated networks. We will provide a foundation for attendees to begin to think about thier problems, how to design and implement them to scale out and take full advantage of the computational power of thousands of processors.

With hundreds of thousands of processors, scientists will tackle problems that to date they had not considered. This will happen in some ways we can not today predict. We will discuss alternative approaches to design of computation of the problem and discuss some examples which have been run on Blue Gene systems, showing actual performance results. More importantly, we will point how having unprecedented number of processors changes one's approach to the computational problem.
