Parameter templates
Depending on the File Format type the Microscopic Parameters can be saved by the acquisition software as metadata with the image file.
Huygens Essential or Huygens Professional reads the metadata from the file when an image is opened. Since not all microscopic parameters in Huygens may be known or included in the metadata - like for example the refractive indexes of the sample medium - we advise users to verify the parameters using the Huygens parameter Wizard or Editor.
The Parameter Wizard and Editor can be accessed via the menu that appears after right clicking on an image in the main Huygens window (see images below). After parameter verification, the Huygens Wizard and Editor offer the possibility to save the microscopic parameters as a template file for future reuse. This makes parameter tuning and confirmation faster and more reliable.

Template files can be loaded at the very start of the Wizard with the Load a template button, or in Editor Window with the Load button. Loading a template allows you to skip the parameters verification stage, provided that an image is to be restored with the same optical properties as the ones which were recorded on the template. Templates can be chosen from a list of pre-saved template files which reside both in the common templates directory and in the user's personal template directory.
You can also choose to load a template file from a different location.
Templates are also used in the Batch Processor.
Location
Templates are saved to disk as files with suffix.hgst. The Huygens common templates directory is named Templates, and resides in the Huygens installation directory, namely /usr/local/svi/Templates on Unix systems, C:\Program Files\SVI\Templates on Windows and /Applications/SVI/Templates on the Mac OS X. The user's personal templates directory is called SVI and it can be found in the user's home directory.
