FAIR Computational Workflows

Abstract (Expand)

Computational workflows describe the complex multi-step methods that are used for data collection, data preparation, analytics, predictive modelling, and simulation that lead to new data products. They … can inherently contribute to the FAIR data principles: by processing data according to established metadata; by creating metadata themselves during the processing of data; and by tracking and recording data provenance. These properties aid data quality assessment and contribute to secondary data usage. Moreover, workflows are digital objects in their own right. This paper argues that FAIR principles for workflows need to address their specific nature in terms of their composition of executable software steps, their provenance, and their development.

Final summary of EuroScienceGateway main achievements, impacts, key results, sustainability data management and exploitation plans

Abstract (Expand)

Description This deliverable provides the final project summary of EuroScienceGateway (ESG), a Horizon Europe and EOSC initiative (Grant Agreement 101057388, Sept 2022–Aug 2025) coordinated by …ed by Albert-Ludwigs-Universität Freiburg. It summarizes ESG’s main achievements, impacts, FAIR data management, sustainability and exploitation plans, and dissemination outcomes. Technically, ESG delivered a production-grade, federated research gateway built on Galaxy and an expanded Pulsar Network, enabling scalable, data-intensive analysis across heterogeneous European compute and storage. Key innovations include Bring-Your-Own-Compute/Storage (BYOC/BYOS), a smart meta-scheduler (TPV Broker), Galaxy Job Radar dashboard, and streamlined deployment/admin tooling—altogether improving throughput, data locality, and operational transparency. The project operationalized FAIR principles for computational workflows by packaging and publishing Workflow RO-Crates with persistent identifiers via WorkflowHub, advancing EOSC interoperability. Federated AAI (e.g., EGI Check-in, LS Login, IAM4NFDI) supports secure access across institutions. ESG contributed >20 workflows, >40 tutorials, and >10 peer-reviewed publications, and collaborated with 20+ initiatives. Six national Galaxy instances and 10+ Pulsar endpoints were launched; the European Galaxy instance achieved ISO/IEC 27001 certification. Community impact was substantial: registered users on the European Galaxy portal grew from ~30,000 to >130,000, with monthly actives doubling to >6,000, underpinned by >20 online/onsite workshops and large-scale training through the Galaxy Training Network and Training-Infrastructure-as-a-Service (TIaaS). Sustainability is ensured through distributed governance, national/institutional hosting of Galaxy/Pulsar services, continued curation of workflows and training materials, and alignment with EOSC service models and funding pathways. The report closes with exploitation routes for beneficiaries and stakeholders and a record of dissemination and outreach activities across the European research ecosystem.

Framework para a Construção de Redes Filogenéticas em Ambiente de Computação de Alto Desempenho

Abstract (Expand)

No presente artigo é apresentado uma avaliação de desempenho de um Framework de Redes Filogenéticas no ambiente do supercomputador Santos Dumont. O trabalho reforça os benefícios de paralelizar o … paralelizar o framework usando abordagens paralelas baseadas em Computação de Alta Vazão (CAV), e Computação de Alto Desempenho (CAD). Os resultados da execução paralela do framework proposto, demonstram que este tipo de experimento da bioinformática é apropriado para ser executado em ambientes de CAD; apesar de que nem todas as tarefas e programas componentes do framework tenham sido criados para usufruir de escalabilidade em ambientes de CAD, ou de técnicas de paralelismo em diferentes níveis. A análise comparativa da execução dos cinco pipelines de forma sequencial (como desenhado e usado originalmente por bioinformatas) apresentou um tempo estimado de 81, 67 minutos. Já a execução do mesmo experimento por meio do framework executa os cinco pipelines de forma paralela e usufruindo de um melhor gerenciamento das tarefas, gerando um tempo total de execução de 38,73 minutos. Essa melhora é de aproximadamente 2, 11 vezes em tempo de execução sugere que a utilização de um framework otimizado leva à diminuição do tempo computacional, à melhora de alocação de recursos e ao tempo de espera na alocação.

Framework para execução de workflows de redes filogenéticas em ambientes de computação de alto desempenho

Abstract (Expand)

In the last years, the development of technologies, such as next-generation sequencing and high-performance computing allowed the execution of Bioinformatics experiments of high complexity and … computationally intensives. Different Bioinformatics fields need to use high-performance computing platforms to take advantage of the parallelism and tasks distribution, through specialized technologies of scientific workflows management systems. One of the Bioinformatics fields that need high-performance computing is phylogeny, a field that expresses the evolutive relations between genes and organisms, establishing which of them are most related evolutively. The phylogeny is used in several approaches, such as in the species classification; in the discovery of individuals’ kinship; in the identification of pathogens origins, and even in conservation biology. A way of representing these phylogenetic relations is using phylogenetic networks. However, the construction of these networks uses computationally intensive algorithms that require the constant manipulation of different input data. This work aims the development of a framework for construction of explicit phylogenetic networks, modeling a scientific workflow that adds different methods for the construction of the networks and the required input data treatment. The framework was developed to allow the use of multiple flows from the workflow in an automated, parallel, and distributed manner in a single execution and also to be executable in high- performance computing environments, constituting a challenging task, once the tools used are not developed focused in this environment. To orchestrate the workflow tasks, the scalable parallel programing library Parsl was used, allowing to do optimizations in the workflow’s tasks execution, performing better management of the resources. Two versions of the framework were developed, called Single Partition and Multi Partition, differing in the manner in which the resources are used. In tests performed, there was an improvement in the execution time of about five times when compared to the sequential execution of a flow without the optimizations. The framework was validated using public data of Dengue virus genomes, which were processed, annotated, and executed in the framework using the Santos Dumont supercomputer. The construction of the genomes’ explicit phylogenetic networks indicates that the framework is a functional, efficient, and easy to use tool.

INSaFLU: an automated open web-based bioinformatics suite “from-reads” for influenza whole-genome-sequencing-based surveillance

Abstract (Expand)

Background A new era of flu surveillance has already started based on the genetic characterization and exploration of influenza virus evolution at whole-genome scale. Although this has been prioritized …d by national and international health authorities, the demanded technological transition to whole-genome sequencing (WGS)-based flu surveillance has been particularly delayed by the lack of bioinformatics infrastructures and/or expertise to deal with primary next-generation sequencing (NGS) data. Results We developed and implemented INSaFLU (“INSide the FLU”), which is the first influenza-oriented bioinformatics free web-based suite that deals with primary NGS data (reads) towards the automatic generation of the output data that are actually the core first-line “genetic requests” for effective and timely influenza laboratory surveillance (e.g., type and sub-type, gene and whole-genome consensus sequences, variants’ annotation, alignments and phylogenetic trees). By handling NGS data collected from any amplicon-based schema, the implemented pipeline enables any laboratory to perform multi-step software intensive analyses in a user-friendly manner without previous advanced training in bioinformatics. INSaFLU gives access to user-restricted sample databases and projects management, being a transparent and flexible tool specifically designed to automatically update project outputs as more samples are uploaded. Data integration is thus cumulative and scalable, fitting the need for a continuous epidemiological surveillance during the flu epidemics. Multiple outputs are provided in nomenclature-stable and standardized formats that can be explored in situ or through multiple compatible downstream applications for fine-tuned data analysis. This platform additionally flags samples as “putative mixed infections” if the population admixture enrolls influenza viruses with clearly distinct genetic backgrounds, and enriches the traditional “consensus-based” influenza genetic characterization with relevant data on influenza sub-population diversification through a depth analysis of intra-patient minor variants. This dual approach is expected to strengthen our ability not only to detect the emergence of antigenic and drug resistance variants but also to decode alternative pathways of influenza evolution and to unveil intricate routes of transmission. Conclusions In summary, INSaFLU supplies public health laboratories and influenza researchers with an open “one size fits all” framework, potentiating the operationalization of a harmonized multi-country WGS-based surveillance for influenza virus.

Large-Scale Protein Interactions Prediction by Multiple Evidence Analysis Associated With an In-Silico Curation Strategy

Abstract (Expand)

Predicting the physical or functional associations through protein-protein interactions (PPIs) represents an integral approach for inferring novel protein functions and discovering new drug targets … during repositioning analysis. Recent advances in high-throughput data generation and multi-omics techniques have enabled large-scale PPI predictions, thus promoting several computational methods based on different levels of biological evidence. However, integrating multiple results and strategies to optimize, extract interaction features automatically and scale up the entire PPI prediction process is still challenging. Most procedures do not offer an in-silico validation process to evaluate the predicted PPIs. In this context, this paper presents the PredPrIn scientific workflow that enables PPI prediction based on multiple lines of evidence, including the structure, sequence, and functional annotation categories, by combining boosting and stacking machine learning techniques. We also present a pipeline (PPIVPro) for the validation process based on cellular co-localization filtering and a focused search of PPI evidence on scientific publications. Thus, our combined approach provides means to extensive scale training or prediction of new PPIs and a strategy to evaluate the prediction quality. PredPrIn and PPIVPro are publicly available at https://github.com/YasCoMa/predprin and https://github.com/YasCoMa/ppi_validation_process.
