Note on Horta versions

The Horta application exists in two versions that come from a common code base. The cloud version (HortaCloud) that is available here is a reduced version of the desktop version (Janelia Workstation). In fact, we’ll often use the word “workstation” to refer to the Horta application in either form.

When there are differences between the two versions, they will be noted with “(HortaCloud)” and “(desktop)”. If the differences are more substantial, they will be presented like this:

The major user-visible differences between the two versions are:

• HortaCloud does not have access to the local file system or clipboard and requires additional steps to import or export data via those routes (see AppStream Basics section for details)
• HortaCloud datasets typically only include low-resolution 2D data, so some 2D tools are not as useful or may not function in the absence of high-resolution data (eg, automatic path tracing)
• the desktop Janelia Workstation contains tools for viewing, annotating, and managing other unrelated Janelia datasets
