Default Settings Editor
The Default Settings Editor is a dialog for configuring default parameter values at two levels: Application Defaults and Workspace Defaults. Setting defaults reduces repetitive configuration when creating new studies.
Defaults Hierarchy
Ephy uses a two-tier defaults hierarchy:
- Application Defaults persist globally across all workspaces. When you create a new workspace, Ephy assigns the Application Defaults to the new workspace's Workspace Defaults.
- Workspace Defaults persist with the individual workspace file. When you create a new study within a workspace, Ephy applies the Workspace Defaults to the new study's parameters.
This means Application Defaults seed new Workspace Defaults, and Workspace Defaults seed new studies. If you always work with the same configuration, set your Application Defaults once and all new workspaces and studies will inherit those values.
Opening the Default Settings Editor

Editing Default Settings
To configure default values:
- Click the Default Settings toolbar button or select Edit > Default Settings.
- Adjust settings in the Application Defaults and/or Workspace Defaults columns.
- Click Save to apply changes.
