"Key-terms", a learning game for conceptual consolidation https://tess.elixir-europe.org/materials/key-terms-a-learning-game-for-conceptual-consolidation A short presentation describing a new participatory method that easily engages course participants in gamestorming and helps to consolidate new knowledge, by collectively agreeing on ways to place concepts in mind maps. "Key-terms" is a classroom game that can be played in a variety of contexts, from group discussions to several forms of Non-Formal learning (e.g. training) events. It helps a lot in engaging a small audience, following any wrap-up (recapitulation) session. Learners capture terms that they find conceptually important and contribute to a merged list. Then they are invited to pin these terms on a cork board in specified ways, such as placing related terms together (clustering), placing high order terms above lower order ones, etc. The instructor/facilitator can intervene at several levels in minimal, non-disturbing interventions, that help to contextualise what is happening. A depiction of how concepts are perceived in a class emerges quickly. This is, in practice, a visual concept map. The technique is being tested in the context of technical training provision, with the help of IT. Training, Instruction, Education Trainers Educators Ontologists 2014-07-06 2017-10-09

200 billion sequences and counting: analysis, discovery and exploration of datasets with EBI Metagenomics https://tess.elixir-europe.org/materials/200-billion-sequences-and-counting-analysis-discovery-and-exploration-of-datasets-with-ebi-metagenomics-ea1b32d5-b113-436c-a7da-8c7d29648d36 EBI metagenomics (EMG, https://www.ebi.ac.uk/metagenomics/) is a freely available hub for the analysis and exploration of metagenomic, metatranscriptomic, amplicon and assembly data. The resource provides rich functional and taxonomic analyses of user-submitted sequences, as well as analysis of publicly available metagenomic datasets held within the European Nucleotide Archive (ENA). EMG has recently undergone rapid expansion, with an over 10-fold increase in data volumes in the first 5 months of 2016. It now houses ~ 50k publicly available data sets, and represents one of the largest collections of analysed metagenomic data. As its data content has grown, EMG has increasingly become a platform for data discovery. To support this process, we have made a series of user-interface improvements, including the classification of projects by biome, presentation of results data for better visualisation and more convenient download, and provision of project level summary files. More recently, we have indexed project metadata for use with the EBI search engine, enabling exploration across different datasets. For example, users are able to search with a particular taxonomic lineage or protein function and discover the projects, samples and sequencing runs in which that lineage or function is found. This functionality allows users to explore associations between biomes, environmental conditions and organisms and functions (e.g., discovering protein coding sequences that correspond to certain enzyme families found in aquatic environments at a given temperature range). Here, we give an overview of the EMG data analysis pipeline and web site, and illustrate the use of the new search facility for data discovery. metagenomics 2016-12-16 2017-01-11

3-day hands-on NGS workshop https://tess.elixir-europe.org/materials/3-day-hands-on-ngs-workshop This document is the trainee exercise booklet for a 3 day hands-on Next Generation Sequencing workshop developed by Bioplatforms Australia, CSIRO and EMBL-EBI.  This workshop is aimed at bench biologists, PhD students or early career postdoctoral researchers or those new to the analysis of NGS data and assumes no prior knowledge of bioinformatics. This course covers the following topics: data quality control, read alignment, ChIPSeq, RNASeq and de novo assembly. The workshop starts with the Intro to the shell material from Software Carpentry (http://software-carpentry.org/v4/shell/index.html).  Introductory lectures on each topic are presented before trainees move on that topic. The workshop has been delivered a number of times in different cities in Australia to date, in a roadshow style, and is designed to run on virtual machines on the Australian research cloud. Trainees then use NoMachine NX client to provide a remote desktop like connection to their own dedicated VM for the duration of of the workshop.  Various contributors made this workshop possible and they are credited in the introduction to each section.

Assessing microbial biogeography by using a metagenomic approach https://tess.elixir-europe.org/materials/assessing-microbial-biogeography-by-using-a-metagenomic-approach-2010019e-528d-4947-9056-e67e089ad240 Soils are highly complex ecosystems and are considered as one of the Earth’s main reservoirs of biological diversity. Bacteria account for a major part of this biodiversity, and it is now clear that such microorganisms have a key role in soil functioning processes. However, environmental factors regulating the diversity of below-ground bacteria still need to be investigated, which limits our understanding of the distribution of such bacteria at various spatial scales. The overall objectives of this study were: (i) to determine the spatial patterning of bacterial community diversity in soils at a broad scale, and (ii) to rank the environmental filters most influencing this distribution. This study was performed at the scale of the France by using the French Soil Quality Monitoring Network. This network includes more than 2,200 soil samples along a systematic grid sampling. For each soil, bacterial diversity was characterized using a pyrosequencing approach targeting the 16S rRNA genes directly amplified from soil DNA, obtaining more than 18 million of high-quality sequences. This study provides the first estimates of microbial diversity at the scale of France, with for example, bacterial richness ranging from 555 to 2,007 OTUs (on average: 1,289 OTUs). It also provides the first extensive map of bacterial diversity, as well as of major bacterial taxa, revealing a bacterial heterogeneous and spatially structured distribution at the scale of France. The main factors driving bacterial community distribution are the soil physico-chemical properties (pH, texture...) and land use (forest, grassland, crop system...), evidencing that bacterial spatial distribution at a broad scale depends on local filters such as soil characteristics and land use when regarding the community (quality, composition) as a whole. Moreover, this study also offers a better evaluation of the impact of land uses on soil microbial diversity and taxa, with consequences in terms of sustainability for agricultural systems. metagenomics 2016-12-16 2017-01-11
