A Critical Guide to the neXtProt knowledgebase: querying using SPARQL https://tess.elixir-europe.org/materials/a-critical-guide-to-the-nextprot-knowledgebase-querying-using-sparql This Critical Guide in the Introduction to Bioinformatics series briefly outlines how to explore the neXtProt human protein database using SPARQL. While text indexation has made database contents more accessible, being able to combine search criteria for specific content permits more powerful querying, and provides a means to mine the information stored in databases. This Guide illustrates the use of the SPARQL semantic query language to interrogate neXtProt and other databases that provide SPARQL endpoints. Specifically, the Guide introduces the concept of database ‘semantic triples’, and examines features of the neXtProt data model. On reading this Guide, and completing the exercises, users will be able to: i) identify key entities within the neXtProt data model; ii) explain what these entities represent, what information they contain and what the information is used for; iii) identify key SPARQL syntax elements; iv) understand SPARQL tutorial examples; and v) write a SPARQL query to retrieve entries matching specific criteria.

A Critical Guide to the UniProtKB Flat-file Format https://tess.elixir-europe.org/materials/a-critical-guide-to-the-uniprotkb-flat-file-format This Critical Guide briefly presents the need for biological databases and for a standard format for storing and organising biological data. Web-based interfaces have made databases more user-friendly, but knowledge of the underlying file format offers a deeper understanding of how to navigate and mine the information they contain, so that humans and machines can get the most out of them. This Guide explores the file format that underpins one of today’s most popular protein sequence databases – UniProtKB. Specifically, this Guide introduces the concept of database ‘flat-files’, and examines features of the UniProtKB flat-file format. On reading this Guide, users will be able to: i) identify key fields within UniProtKB/Swiss-Prot and UniProtKB/TrEMBL flat-files; ii) explain what these fields mean, what information they contain and what the information is used for; iii) analyse the information in different fields and infer structural and functional features of a sequence; iv) examine and investigate the provenance of annotations; and v) compare annotations at different time-points and evaluate the likely impact of annotation changes.

Clinical Bioinformatics I - Tutor notes https://tess.elixir-europe.org/materials/clinical-bioinformatics-i-tutor-notes Clinical Bioinformatics I is a 10 credit module of the new MSc in Clinical Bioinformatics, delivered by Nowgen/NGRL and the University of Manchester in the UK. Clinical Bioinformatics is one of the streams of the NHS Scientific Training Programme (STP). The programme is a mixture of work placement based training interspersed with academic teaching.  The tutor notes describe the content taught on each day of the 5 day course, and the approach used to teach the materials. Each day is divided into two parts, a series of lectures in the morning to introduce the topics, then the afternoon sessions present a series of case studies for the students to work through in a 'problem based learning (PBL) approach to reinforce the lecture content.  Clinical bioinformatics, Genomics, Introduction bioinformatics Life Science Researchers healthcare professionals postgrad 2013-11-28 2017-10-09

eBioKit https://tess.elixir-europe.org/materials/ebiokit Extensive teaching experience gained by conducting bioinformatics training courses in Kenya, Uganda, Mauritius (UoM), SriLanka, Sweden, Chile and Zimbabwe showed that it was difficult to successfully teach and demonstrate several bioinformatics resources, due to and often limited by slow Internet access. For that reason a bioinformatics platform, eBioKit  was engineered to ease the administrative burden of regularly updating large databases and installing software. This platform contains more than 300 bioinformatics applications (EMBOSS, Galaxy, Blast, RSAT etc),  and most relevant databases (ENSEMBL, Uniprot, OMIM, PDB, etc) locally, solving the network speed related problems and problems associated with the installation of software. Version 2 of this system has been successfully tested in real world situations both for capacity building and research in Kenya at ILRI, the Biosciences eastern and central Africa (BecA), KEMRI Wellcome Trust Research Programme (KWTRP) and The International Centre of Insect Physiology and Ecology (ICIPE). The system has further been deployed in the SANBio bioinformatics network in Southern Africa (10 countries) and Sri Lanka (Version 1) and has recently been adopted by the H3ABioNet African Bioinformatics Network as a platform to provide bioinformatics training and bioinformatics computing services at nodes in the network (http://www.h3abionet.org).  Advanced bioinformatics training, Introduction bioinformatics Bachelor students Bench biologists Life Science Researchers PhD students 2013-10-03 2017-10-09
