Integrative meta-analysis of public and novel vertebrate BBB omics data and establishment of the BBBhub platform
ESR4 established the BBBHub with core functionalities and implemented the corresponding server infrastructure. As a framework for the BBBHub, we used openBIS1 – a flexible framework for managing and analyzing complex data in biology research – and developed several add-ons and modifications. They include modifications to the user authentication user spaces to account for privacy and security, the implementation of a data upload system and the establishment of metadata fields. These are required for organization, analysis, searchability and communication between the user side, the openBIS system and the compute cluster. ESR4 implemented a Snakemake2 based RNA-Seq analytical pipeline. This pipeline ensures consistency in the analysis of the uploaded raw data allowing comparisons across datasets. The result files can be downloaded and visualized natively.
Currently, ESR4 is optimizing the BBBHub for public launch by improving the search systems, changing the graphical user interface to become more user-friendly and adding publicly available datasets. The public launch is scheduled to Q1 of 2020.
ESR4 also worked closely with other ESRs, particularly in experimental design, in-depth data analysis and results interpretation of the projects of ESR8 and ESR12. ESR4 also wrote a RNA-Seq in Brain Barriers guidelines paper together with ESRs 6, 7, 8 and 12. The objective is to provide best practices for experimental design and publication in the field.
