The iso contours module is designed to compare the values in the simulation to standards or expectations.
The window contains two widgets :
the settings widgets on the left contains settings to define the filters applied to the image and the iso contours color map and segments,
the preview widget on the right contains a preview of the image : you can select a layer to display and analyse.
Using this module, the save button has the following options :
LDR output : the processed output (the image currently displayed on screen) saved to a *.png file.
In order to smooth the iso contours, you can apply a median filter or a gaussian filter to the simulation.

The iso contours and segments sections define what is actually analysed and how :
The channel defines which channel is analysed from the layer selected in the texture widget.
The mode, color map and contours color define the visual aspect of the output. The Mode defines how the isocontours are drawn in the image : see examples bellow.
Mode "Zones" : each zone is drawn using the same colour, contours are drawn in a given colour
Mode "Contours" : each isocontour is drawn in a different colour, background is uniform
Mode "Overlay" : each zone is drawn using the original colour, contours are drawn in a given colour
The iso lines are placed at specific values defined in the segments section. The segments can be regularly spaced along the [min,max] values in the simulation, or they can be given manually for specific values.
You can save, copy and import these segments to be able to reuse the same display settings in different simulations.
