On the JR you don't need to download the application - access will be obvious, or assisted by JRSO staffask JRSO personnel if the application is not installed on the workstation.
Correlator installs a directory for its internal database at a default location that looks something like this:
...
Figure 1-2. Correlator File menu.
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).

Correlator operates within a single window that can be expanded as much as available monitor space permits. The window can be toggled between When launching Correlator, you land on the Data Manager view (Fig. 2.1-1) and . You can toggle to the Display view (next section). To navigate between these views, use the by using the Go to Display button in the lower left corner of either window (Figs. 2.1-2)the window.

The Data Manager view has two functional tabs across the top:
- The Data Manager tab (Fig. 2. X2-1) 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).
The function in the Data Manager view are described in the Manage data in Correlator section.
2.2. Display view
Correlator operates within a single window that has two major views: Data Manager view (previous section) and The second and main view in Correlator is the Display view (Fig 2.2-1). The views can be toggled with the You can toggle back to the Data Manager view by using the Go to Data Manager button in the lower left corner of either window (Figs. 2.2-2)the window.

The Display view has three areas, two for data plotting and one for the functional controls, organized in four control tabs.:
- Left plot area for depth shifting
- Right plot area for splicing (can be toggled off in the
- 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 if more display space is preferred for depth shifting, see below)
- Control function area on the far right.

- Splice Cores: This tab has controls for splicing, which are described in the Construct the splice section.

Data Filters tab
The Data Filters controls are largely self-explanatory but require some commentary (Fig. 2.2-3).
- Data filters are applied to the data from all cores for a specified data type. For a more specific filtering of known intervals with severe core disturbance, etc., you have the option to apply a file with those intervals specified in the Correlator Downloader application, at the time of data download.
- At this time, data culling can only be specified for top of cores (to remove data from “exotic” material washed down from higher up in the hole). A future version will include culling from core bottoms (“exotic” material “sucked in” when the piston core was removed) and culling from section ends (“edge effect”).
- Some odd behavior has been observed when deleting a cull filter under certain circumstances, and this has not yet been repaired (no user pressure). An easy workaround is to re-load the data.

Shown is a 9-point Gaussian filter applied to the magnetic susceptibility data whereby both original and smoothed (white trace overlay) are plotted. The filter filters can be edited or deleted.
