1. About Correlator 4.0
The Correlator application facilitates stratigraphic correlation of cores from multiple holes at a drill site. Its features support

Affine tables created in Correlator versions 3 and 4 differ from those in version 2: they include additional information (last three columns, see Appendix 2) that allow Correlator to reconstruct the relationship between cores. Affine tables created in the production version, 2.1_rc2 can still be imported in 4.0 by right-clicking "Saved Tables" in the Data Manager (available once data are loaded) and choosing Import legacy affine table. However, because legacy affine tables have no record of the reference core used to create a TIE, all cores shifted by a TIE will be converted to status REL on import into 4.0. This has no effect on their cumulative offsets, which will be preserved, but users will have to rebuild the TIEs manually (as was the case in version 2).

2. Correlator basic functions overview
2.1. Data Manager and Display views
Correlator operates within a single window that can be expanded as much as available monitor space permits. The window can be toggled between the Data Manager view (Fig. 2.1-1) and the Display view (Fig 2.1-2). To navigate between these views, use the top button on the floating tool bar (Figs. 2.1-1 and 2.1-2), which is always available on top of either view unless turned off in the View menu.
Figure 2.1-1. Data Manager view. Also shown is the floating tool bar, where the top button can be used to toggle to the Display view.
The Data Manager view has two functional tabs across the top:
- The Data Manager tab (Fig. X) lists the files imported into Correlator and provides the functions for adding and managing the data in Correlator.
- The Generic Data tab displays data from files being imported when such an import is triggered in the Data Manager tab (otherwise it’s an empty grid).
Figure 2.1-2. Display view, with the Display Preferences tab open on the right.
The Display view has three areas, two for data plotting and one for the functional controls, organized in four control tabs.
- The left plot area is for depth shifting, and the corresponding controls are in the Shift Cores tab.
- The right plot area is for the construction of splices, and the corresponding controls are in the Splice Cores tab. This plot area can be turned off at the top of the Display Preferences tab (shown in Fig. X) if more display space is preferred for depth shifting.
- The control area can be toggled among the following four tabs:
- Close: This tab acts like a button and closes the control panel. The control panel can be opened again by clicking any of the other four tabs.
- Shift Cores: This tab has controls for depth shifting, which are described in the Depth shift cores section.
- Splice Cores: This tab has controls for splicing, which are described in the Construct the splice section.
- Display Preferences: This tab has general data display controls, as shown in Fig. X.
- Data Filters: This tab offers data filtering options, including decimate, smooth and cull (Fig. X).
