Heterogeneous data from electrophysiological experiments and spiking neural network simulations exhibits a level of complexity that puts tools to design workflows for managing data acquisition and analysis in a reproducible way in high demand [1]. Here, following [2], we demonstrate a use case in the framework of the Human Brain Project (HBP) that supports such analysis workflows in a collaborative fashion by combining various software components hosted on a common platform. The emerging open-source software tools that represent the basis of the pipelines are, in particular: (i) electrophysiological data of different origins are represented in a standard description using the Neo framework [3], (ii) complex metadata accumulating in the electrophysiological experiment [4] are recorded and organized using the open metadata markup language (odML) [5], and (iii) analysis is performed using the Electrophysiology Analysis Toolkit (Elephant, http://neuralensemble.org/elephant/) as a recent community-centered modular analysis framework for multi-scale activity data, such as massively parallel spike data or local field potentials. We outline how the integration of this workflow into the HBP Collaboratory infrastructure (http://www.collab.humanbrainproject.eu) facilitates interdisciplinary, collaborative work including access to high-performance computing for advanced analysis approaches.AcknowledgementsHelmholtz Portfolio Theme Supercomputing and Modeling for the Human Brain (SMHB), EU grant 720270 (Human Brain Project, HBP).References Badia, R. et al.
