They produce triacyl-glycerides (TAG) which are easily converted into biofuel. When exposed to nitrogen limitation, Data/ Application Klok, Maria Suarez Diez, triacylglycerol production in Neochloris Neochloris oleoabundans accumulates up to 40% of its dry weight in TAG. However, a feasible production requires a decrease of production costs, which can be partially reached by Application Lenny de Jaeger, Mark oleoabundans increasing TAG yield.We built a constraint-based model describing primary metabolism of N. oleoabundans. It was grown in combinations of light absorption and nitrate supply rates and the poster Sturme, Packo Lamers, parameters needed for modeling of metabolism were measured. Fluxes were then calculated by flux balance analysis. cDNA samples of 16 experimental conditions were sequenced, Rene' Wijffels, Vitor Dos assembled and functionally annotated. Relative expression changes and relative flux changes for all reactions in the model were compared.The model predicts a maximum TAG yield on light Santos, Peter Schaap of 1.07g (mol photons)-1, more than 3 times current yield under optimal conditions.

Faculty OF Science AND TECHNOLOGY Department OF Computer Science TOWARD ReprODUCIBLE Analysis AND ExplorATION OF High-ThrOUGHPUT Biological Datasets — Bjørn Fjukstad A DISSERTATION FOR THE DEGREE OF Philosophiae Doctor – 2018 This thesis document was typeset using the UiT Thesis LaTEX Template. © 2018 – http://github.com/egraff/uit-thesis “Ta aldri problemene på forskudd, for da får du dem to ganger, men ta gjerne seieren på forskudd, for hvis ikke er det altfor sjelden du får oppleve den.” –Ivar Tollefsen AbstrACT There is a rapid growth in the number of available biological datasets due to the advent of high-throughput data collection instruments combined with cheap compute infrastructure. Modern instruments enable the analysis of biological data at different levels, from small DNA sequences through larger cell structures, and up to the function of entire organs. These new datasets have brought the need to develop new software packages to enable novel insights into the underlying biological mechanisms in the development and progression of diseases such as cancer. The heterogeneity of biological datasets require researchers to tailor the explo- ration and analyses with a wide range of different tools and systems. However, despite the need for their integration, few of them provide standard inter- faces for analyses implemented using different programming languages and frameworks. In addition, because of the many tools, different input parame- ters, and references to databases, it is necessary to record these correctly. The lack of such details complicates reproducing the original results and the reuse of the analyses on new datasets. This increases the analysis time and leaves unrealized potential for scientific insights. -
Blastjs: a BLAST+ Wrapper for Node.Js
Page et al. BMC Res Notes (2016) 9:130 DOI 10.1186/s13104-016-1938-1 BMC Research Notes TECHNICAL NOTE Open Access blastjs: a BLAST wrapper for Node.js Martin Page1, Dan MacLean1 and Christian+ Schudoma1,2* Abstract Background: To cope with the ever-increasing amount of sequence data generated in the field of genomics, the demand for efficient and fast database searches that drive functional and structural annotation in both large- and small-scale genome projects is on the rise. The tools of the BLAST suite are the most widely employed bioinformatic method for these database searches. Recent trends in bioinformatics+ application development show an increasing number of JavaScript apps that are based on modern frameworks such as Node.js. Until now, there is no way of using database searches with the BLAST suite from a Node.js codebase. + Results: We developed blastjs, a Node.js library that wraps the search tools of the BLAST suite and thus allows to easily add significant functionality to any Node.js-based application. + Conclusion: blastjs is a library that allows the incorporation of BLAST functionality into bioinformatics applications based on JavaScript and Node.js. The library was designed to be as user-friendly+ as possible and therefore requires only a minimal amount of code in the client application. The library is freely available under the MIT license at https:// github.com/teammaclean/blastjs.

Anatomy of Biojs, an Open Source Community for the Life Sciences
FEATURE ARTICLE elifesciences.org CUTTING EDGE Anatomy of BioJS, an open source community for the life sciences Abstract BioJS is an open source software project that develops visualization tools for different types of biological data. Here we report on the factors that influenced the growth of the BioJS user and developer community, and outline our strategy for building on this growth. The lessons we have learned on BioJS may also be relevant to other open source software projects.

Visually Guiding Users in Selection, Exploration, and Presentation Tasks

Marc Streit Visually Guiding Users in Second Examiner Prof. Dr. Tobias Schreck Selection, Exploration, March 2017 and Presentation Tasks Doctoral Thesis to obtain the academic degree of Doktor der technischen Wissenschaften in the Doctoral Program Technische Wissenschaften JOHANNES KEPLER UNIVERSITY LINZ Altenbergerstraße 69 4040 Linz, Osterreich¨ www.jku.at DVR 0093696 Abstract Making scientific discoveries based on large and heterogeneous datasets is challenging. The continuous improvement of data acquisition technologies makes it possible to collect more and more data. However, not only the amount of data is growing at a fast pace, but also its complexity. Visually analyzing such large, interconnected data collections requires a user to perform a combination of selection, exploration, and presentation tasks. In each of these tasks a user needs guidance in terms of (1) what data subsets are to be investigated from the data collection, (2) how to effectively and efficiently explore selected data subsets, and (3) how to effectively reproduce findings and tell the story of their discovery. On the basis of a unified model called the SPARE model, this thesis makes contributions to all three guidance tasks a user encounters during a visual analysis session: The LineUp multi-attribute ranking technique was developed to order and prioritize item collections. It is an essential building block of the proposed guidance process that has the goal of better supporting users in data selection tasks by scoring and ranking data subsets based on user-defined queries. -

Abriata ID Laboratory for Biomolecular Modeling, École Polytechnique Fédérale de Lausanne and Swiss Institute of Bioinformatics, CH-1015 Lausanne, Switzerland; luciano.abriata@epfl.ch; Tel.: +41-021-69-30963 Academic Editor: Igor I. Baskin Received: 11 August 2017; Accepted: 20 August 2017; Published: 24 August 2017 Abstract: Whereas server-side programs are essential to maintain databases and run data analysis pipelines and simulations, client-side web-based computing tools are also important as they allow users to access, visualize and analyze the content delivered to their devices on-the-fly and interactively. This article reviews the best-established tools for in-browser plugin-less programming, including JavaScript as used in HTML5 as well as related web technologies. Through examples based on JavaScript libraries, web applets, and even full web apps, either alone or coupled to each other, the article puts on the spotlight the potential of these technologies for carrying out numerical calculations, text processing and mining, retrieval and analysis of data through queries to online databases and web services, effective visualization of data including 3D visualization and even virtual and augmented reality; all of them in the browser at relatively low programming effort, with applications in cheminformatics, structural biology, biophysics, and genomics, among other molecular sciences. Keywords: JavaScript; HTML; programming; data analysis; internet 1. Introduction Slightly over 20 years ago, a small commentary by Prof. L. Stein in Trends in Genetics anticipated the impact that “web applets” were to have on how scientists browse, visualize, and analyze biological data available online [1]. -
