Though smaller in volume, the corresponding metadata describing the production, pedigree, and ontology, is just as important as the raw data to the scientific discovery process. Driven by the application needs of a number of large-scale distributed workflows, we develop a metadata capturing and analysis system called MPO (short for Metadata, Provenance, Ontology). It seamlessly integrates with most data analysis environments and requires a minimal amount of changes to users' existing analysis programs. Users have the full control of how to instrument their programs to capture as much or as little information as they desire. Once captured in a database system, the workflows can be visualized and studied through a set of web-based tools. In large scientific collaborations where the workflows have been built up over decades, this ability to instrument the complex existing workflows and visualize the key interactions among the software components is tremendously useful.Mon Dec 11 10:26:09 CET 2017Selected Papers from the CLARIN Annual Conference 2015, October 14–16, 2015, Wroclaw, Poland12394-107Research Data Workflows: From Research Data Lifecycle Models to Institutional Solutions2015imported forschungsdaten workflow Tue Sep 12 14:04:34 CEST 2017Behavior Research Methods062542--552The TimeStudio Project: An open source scientific workflow system for the behavioral and brain sciences482016software workflow scientific softwareLizenzMotivation repository 01This article describes a new open source scientific workflow system, the TimeStudio Project, dedicated to the behavioral and brain sciences. The program is written in MATLAB and features a graphical user interface for the dynamic pipelining of computer algorithms developed as TimeStudio plugins. TimeStudio includes both a set of general plugins (for reading data files, modifying data structures, visualizing data structures, etc.) and a set of plugins specifically developed for the analysis of event-related eyetracking data as a proof of concept. It is possible to create custom plugins to integrate new or existing MATLAB code anywhere in a workflow, making TimeStudio a flexible workbench for organizing and performing a wide range of analyses. The system also features an integrated sharing and archiving tool for TimeStudio workflows, which can be used to share workflows both during the data analysis phase and after scientific publication. TimeStudio thus facilitates the reproduction and replication of scientific studies, increases the transparency of analyses, and reduces individual researchers' analysis workload. The project website ( http://timestudioproject.com ) contains the latest releases of TimeStudio, together with documentation and user forums.
