Intervals

It is a common use case to aggregate data over geologically interesting depth intervals. A user may, for instance, wish to create a concentration export differenting between higher and lower density regions of the core, rather than one line per 8 mm (default mode).

The Intervals feature in Insight allows the user to customize and define new intervals, in addition to those that are automatically created.

Caution

The intervals are saved as part of the Project; remember to always save your project, to avoid losing changes to the intervals.

To toggle this feature, pick Show → Intervals in the menu bar.

The Intervals side bar will now be visible to inside the Preview area:

Boundaries are selected and manipulated inside this side bar. Boundaries are also shown inside the Preview as horizontal lines, when sufficiently zoomed in. In order to not clutter the Preview, the lines are automatically hidden when zoomed out.

Selecting Intervals

An interval can be selected by left-clicking it in the Intervals side bar, which then sets its depth range as the selected segment in the Preview.

It is also possible to select several intervals at once, by left-click dragging over all the intervals that are to be included.

Initial Boundaries

Boundaries are initially inserted at the top and bottom of each sample (scanned section of core).

Note

The top-most boundary, the bottom-most boundary, and boundaries which represent discontinuities in depth are immutable, which means that they can neither be removed nor moved.

Adding a Boundary

New boundaries may be added by right-clicking while hovering a current interval. The clicked interval is thereby subdivided into two smaller ones.

Removing a Boundary

An existing boundary can be removed by right-clicking it. The two intervals previously divided by the point are thereby merged into a single larger one.

Notice the difference between removing a user-defined boundary, versus removing one of the initial boundaries. When the latter type is removed, a light blue line is still seen inside the Preview :

Light blue lines thereby mark "special" positions, which allow to more easily restore the original boundaries if needed.

Moving a Boundary

To move an existing boundary, click and drag it with the right mouse button ; other boundaries can also be passed on the way.

Note that when two boundaries are moved on top of each other, they will be merged into a single boundary.
