URPP Adaptive Brain Circuits in Development and Learning (AdaBD)

HDDA Platform

High-dimensional data science platform

The project

Our work at the high-dimensional data analysis (HDDA) platform is based on the assumption that a substantial part of data analysis tasks in neuroscience and beyond can be broken down to a relatively small number of primitives. These primitives are made available to combine in a Lego-like setting within a graphical user interface (GUI) combined with an underlying data-science programming platform. This software package (GUI and underlying platform) is called Dataspace (dspace) and has been conceived of and developed in the last years at ETHZ and UZH by Sepp Kollmorgen, who is now the platform manager. In dspace, code-based workflows and GUI-based workflows ideally merge seamlessly, enabling analyses without coding but also integration with users’ existing code and analysis pipelines at maximal ease. Data in dspace and expansions of dspace can be easily shared. The dspace software, dspace documentation, associated services and materials are currently available in-house to researchers of the URPP AdaBD. We also plan to release a publicly available version of dspace.

In 2022 und 2023, in collaboration with several research groups in and outside the URPP AdaBD, we significantly improved the structure and design of dspace and added capabilities that extend dspace to new forms of data, including light-sheet microscopy data (in particular data produced by the mesoSPIM platform), and behavioural and neural data (i.e. unimodal und multimodal time series data), including, but not limited to, video-, audio-, electrophysiology-, 2-photon-imaging-data, as well as, more generally, data held in the Datajoint- or other table-based-formats. Dspace is especially useful for large datasets (terabyte scale).

Services of the platform

  • Onboarding of new users including discussion of needs with respect to data-analysis/data-science
  • Instruction and training on how to use dspace to meet the user’s needs
  • Download of dspace, dspace documentation, and associated materials, such as video tutorials
  • Integration with other platforms of the URPP AdaBD, e.g. with the mesoSPIM platform
  • Organization of user meetings and outreach activities
  • Customization/extension of dspace to accomodate new types of data and analysis as well as to increase robustness and ease of use.
