Open source projects

    We have developed the META-pipe pipeline for marine metagenomics data analysis. Version 2.0 consists of several backend systems, servers, and services:

    1. Marine Metageonomics Portal. Marine reference databases and more.
    2. Galaxy pipeline provided as part of the NeLS infrastructure. It is intended for Norwegian users so a a FEIDE account is needed for login.
    3. Spark based backend.
    4. Authorization server integrated with Elixir AAI.
    5. Web application frontend.
    6. Object storage server.
    7. Tool to setup META-pipe backend on the OpenStack cPouta cloud.
    8. Tool to setup META-pipe backend on OCCI enabled endpoints.
    Soruce code for META-pipe 1.0 is in the following repositories. Note that these are not maintained anymore.
    1. META-pipe 1.0. Implemented for execution on HPC clusters.
    2. Patches for META-pipe specific metarep (1.4.0) sequence retrieval modifications.
