abstract = {The degree of complexity in analyzing massively parallel,
heterogeneous data from electrophysiological experiments and
network simulations requires work to be performed in larger,
multi-disciplinary collaborations that require the
availability of robust workflows [1,2] and powerful
computing resources [3]. The Human Brain Project (HBP) aims
at creating and operating a scientific research
infrastructure for the neurosciences to address such needs
for integrative software environments. At its core, the HBP
features the Collaboratory, a web-based platform to jointly
implement research projects. Powerful as this approach is in
theory, it is less clear how these developments are most
effectively integrated into the daily work routines of the
researchers analyzing the data.Here, we show how diverse
tools can be successfully combined into a collaborative
analysis workflow hosted on the HBP Collaboratory,
reproducing [5]. Data are represented in the Neo framework
[6], complex metadata [7] are managed using the odML
standard [8], and the main analysis is performed by the
Elephant library (http://python-elephant.org). These
domain-specific tools are combined with generic tools (e.g.,
version control systems) to form a blueprint for performing
collaborative work including access to high-performance
computing. Finally, we outline how these building blocks can
be assembled into formalized workflows to support
reproducible research, e.g., the validation of network
simulations.References:[1] Badia, R., Davison, A., Denker,
