Dips > Data Processing > Query Data
A valid query can consist of a single expression (e.g. TYPE == joint), or it may consist of a complex combination of expressions, using AND, OR and brackets ( ). The following examples illustrate some typical queries that you might use in Dips.
TYPE == joint && SURFACE Includes rough
TYPE == joint && SURFACE == rough && SPACING <= 1
TYPE == fault || TYPE == shear
SPACING > 0.5 && SPACING < 1.5
TYPE == joint && ( TRAVERSE == 1 || TRAVERSE == 2)
The examples are based on the example.dip file which you should find in the Examples folder in your Dips installation folder. To start:
Open the example.dip file.
Select Query Data from the toolbar or the Analysis menu.
