Materials for the tutorial that was given in Taipei on Apr 2, 2019. The tutorial was 3x90 minutes long.

The webpage and abstract of the tutorial is available at https://indico4.twgrid.org/indico/event/8/session/9/?slotId=0#20190402

The main objective of this session is to show how EOSC services can be used for managing active research data (i.e. data transfer, storage, and sharing) and for preserving final research data (i.e. data archiving and publishing). During this training, we will give a brief overview of the EUDAT Services in the data life cycle and demonstrate how these services operate and integrate with each other to meet the data management requirements of research communities and comply with the FAIR principles - which require the data to be properly documented, annotated, archived, published and accessible to the wider community.

This training track is relevant for researchers, IT support people, and service providers who operate services for Open Science.

DEEP-Hybrid-DataCloud project aims to promote the integration of specialized, and expensive, hardware under a Hybrid Cloud platform, so it can be used on-demand by researchers of different communities.

XDC project aims at address high-level topics ranging from the federation of storage resources with standard protocols, the policy driven data management based on Quality of Service, data lifecycle management, metadata handling and manipulation, data preprocessing and encryption during ingestion, and smart caching solutions among remote locations.

This training session will provide practical overview on the solutions implemented both at the level of IaaS, PaaS and SaaS within the projects: INDIGO-DataCloud, eXtreme DataCloud (XDC) and DEEP-HybridDataCloud.

The main objective of this session is to demonstrate how end-users can perform data analysis on large volume of datasets, and produce reusable results following the FAIR principles. During this training track, the latest features of the EGI DataHub, including the interoperability with the EGI Jupyter Notebooks and the EUDAT B2Handle and B2Find services, will be also introduced.

This training track is relevant for researchers, IT support people, and service providers who operate services for Open Science.

In the series of workshops on FAIR services for research data that OpenAIRE is jointly organizing with FAIRsFAIR, EOSC hub and RDA-Europe, the second workshop took place as a part of the larger event ‘Linking Open Science in Austria’. The series of workshops explores: how data infrastructures can work together to meet the challenges of creating, managing, opening and archiving FAIR data.

The aim of the workshops is to:

• Look at the landscape of data infrastructures looking to integrate FAIR into their services
• Set initial recommendations and to find out what the challenges and priorities are

The interactive workshop "Services to Support FAIR Data" had a similar structure as the first workshop in the series of three but was aimed at researchers and research support.

Elastic Cloud Computing Cluster (EC3) is a tool to create elastic virtual clusters on top of Infrastructure as a Service (IaaS) providers, either public (such as Amazon Web Services, Google Cloud or Microsoft Azure) or on-premises (such as OpenNebula and OpenStack). We offer recipes to deploy TORQUE (optionally with MAUI), SLURM, SGE, HTCondor, Mesos, Nomad and Kubernetes clusters that can be self-managed with CLUES: it starts with a single-node cluster and working nodes will be dynamically deployed and provisioned to fit increasing load (number of jobs at the LRMS). Working nodes will be undeployed when they are idle. This introduces a cost-efficient approach for Cluster-based computing.

The target group of the training is developers and administrators of services that want to integrate to ELIXIR AAI for user authentication and authorisation. The training has hands-on sessions for the participants to integrate their own service (or, a test service provided by the trainers) to ELIXIR AAI.

Keywords: AAI, OpenID Connect, Authentication

Target audience: service administrators in organizations that want to make use of ELIXIR AAI

Difficulty level: Intermediate

Authors: Michal Prochazka, Dominik Frantisek Bucik

On this page, you can find the links to the HADDOCK and metadynamics (using Gromacs) tutorials given during the BioExcel Summer School on Biomolecular Simulations 2019 in Pula, Italy.

The first tutorial demonstrates the use of cross-linking data from mass spectrometry to guide protein-protein docking in HADDOCK.

The second tutorial illustrates how metadynamics can be used to sample conformations of a binding pocket; those are subsequently used for docking a ligand using HADDOCK. The conformational sampling approach is following the EDES approach described in the following publication:

• A. Basciu, G. Malloci, F. Pietrucci, A.M.J.J. Bonvin and A.V. Vargiu. Holo-like and druggable protein conformations from enhanced-sampling of binding pocket shape. J. Chem. Inf. and Mod. 59, 1515-1528 (2019).

DisVis is a software developed in our lab to visualise and quantify the information content of distance restraints between macromolecular complexes. It is open-source and available for download from our Github repository. To facilitate its use, we have developed a web portal for it.

This tutorial demonstrates the use of the DisVis web server. The server makes use of either local resources on our cluster, using the multi-core version of the software, or GPGPU-accelerated grid resources of the EGI to speed up the calculations. It only requires a web browser to work and benefits from the latest developments in the software based on a stable and tested workflow. Next to providing an automated workflow around DisVis, the web server also summarises the DisVis output highlighting relevant information and providing a first overview of the interaction space between the two molecules with images autogenerated in UCSF Chimera.

The case we will be investigating is the interaction between two proteins of the 26S proteasome of S. pombe, PRE5 (UniProtKB: O14250) and PUP2 (UniProtKB: Q9UT97). For this complex seven experimentally determined cross-links (4 ADH & 3 ZL) are available (Leitner et al., 2014). We added two false positive restraints - it is your task to try to identify these! For this, we use DisVis to try to filter out these false positive restraints while assessing the true interaction space between the two chains. We will then use the interaction analysis feature of DisVis that allows for a more complete analysis of the residues putatively involved in the interaction between the two molecules. To do so, we will extract all accessible residues of the two partners, and give the list of residues to DisVis using its interaction analysis feature. Finally, we will show how the restraints can be provided to HADDOCK in order to model the 3D interaction between the 2 partners.

This tutorial will demonstrate the use of HADDOCK for predicting the structure of a protein-protein complex from NMR chemical shift perturbation (CSP) data. Namely, we will dock two E. coli proteins involved in glucose transport: the glucose-specific enzyme IIA (E2A) and the histidine-containing phosphocarrier protein (HPr).

The structures in the free form have been determined using X-ray crystallography (E2A) (PDB ID 1F3G) and NMR spectroscopy (HPr) (PDB ID 1HDN). The structure of the native complex has also been determined with NMR (PDB ID 1GGR).

These NMR experiments have also provided us with an array of data on the interaction itself (chemical shift perturbations, intermolecular NOEs, residual dipolar couplings, and simulated diffusion anisotropy data), which will be useful for the docking. For this tutorial, we will only make use of inteface residues identified from NMR chemical shift perturbation data as described in Wang et al, EMBO J (2000).
