Getting started

  • What is the quickest way to get started with WEBKNOSSOS?

    Signing up for a free account on webKnossos.org is the quickest way to get started with webKnossos. The Basic plan get's you started for quick streaming and annotation of large-scale volumetric datasets. For larger teams and more demanding projects we recommend the Team and Power plans.
    webKnossos.org makes it easy for you to get started. No installation required - it just runs in your browser. Best of all, it comes with regular updates, backups, storage and secure hosting all taken care of.

  • How can I view and annotate my datasets on webknossos.org?

    webKnossos.org comes with a built-in interface for uploading and importing datasets right from the browser to quickly get you started. Alternatively, webKnossos supports streaming you data from remote storage (e.g. S3, GCS, HTTP) in the OME-Zarr, N5, Neuroglancer Precomputed file formats. Get in touch with us if you need assistance with importing data into webKnossos.
    On the Power plan, we offer managed on-premise installations of webKnossos, where datasets can be directly stored in your data center. 

  • Where can I learn more about WEBKNOSSOS?

    webKnossos offers a wide array of tools to manage large 3D datasets and annotate them efficiently. Learn more about webKnossos and its functionality on our features overview page.

    Check out the webKnossos user documentation to learn more about all annotation modes and their settings. Alternatively, get in touch with us and one of our webKnossos experts will help you get started.

    Make sure to follow webKnossos on Twitter and sign up for our newsletter to get updates about the latest features .

General

  • Can I further analyze my annotations outside of WEBKNOSSOS with Python/MATLAB?

    Yes, you can. webKnossos allows the download and export of skeleton annotations as NML files and segmentations/volume data as binary/wkw files or Tiff-stacks. Further, you can access segmentation data through the Zarr streaming interface. 
    See the documentation on tooling for a recommendation of open-source Python/MATLAB libraries to work with the webKnossos formats.
    We offer managed on-premise installations of webKnossos, where datasets can be directly stored in your data center. Get in touch with us to learn more.

  • How can I access datasets publicly published on webknossos.org?

    There is a collection of published datasets on webknossos.org. All users may freely browse the image datasets and accompanying annotations without a login. Creating a free account will allow to download the data and create custom annotations on top of these datasets.

  • I am looking for a custom WEBKNOSSOS setup.

    webKnossos can be set up to accommodate flexible deployment scenarios. Over the years we have worked with different research institutes and have tackled a diverse set of challenges. Custom data formats, petabyte-scale datasets, on-premise or cloud storage, file system tuning, monitoring...
    Our Power plan that can be set up as on-premise installations are right for you. Talk to our webKnossos experts about custom solutions.

  • I need a new functionality not yet available in WEBKNOSSOS.
