If working with other data, all you you have to make is that they have a depth column and a value column, and place the in the site folder.

As soon as the first data file is imported, Correlator creates a data directory for the site, using the site name from the data file, and a number of data type folders that are explained in the Add new data section. An example corresponding the user directory example is shown in Fig. 3-2. The Correlator directory displays in the hierarchical order Site/Data type/Hole, sorted alphabetically at each level.

You can access numerous data management functions from context menus (right-click) at each directory level. Table 3-1 lists all the functions and tabulates the directory levels and data types where they are accessible. Figure 3-3 shows the corresponding menu windows.
Table 3.2-1. Summary of data management functions.
Function ( |
menu item) | Function description | Root level - no data yet (Fig. 3.2- |
1a) | Site level - most used (Fig. 3.2- |
1b) | Non-image data type level (Fig. 3.2- |
1c) | Image data type level (Fig. 3.2- |
1d) | Saved Tables (Fig. 3.2- |
1e) | Site Summaries (Fig. 3.2- |
1f) | |||||||
Add new data | Import data from directory | YES | YES | YES | |||
Load | Load data for plotting in Display view. | YES | YES | YES | |||
Update | The specified file is re-imported and the information in Correlator is updated. | YES | YES | YES | |||
Delete | Remove from the Correlator database. | YES | YES | YES | |||
Disable/Enable | Disable or Enable (should read “Enabled” and “Disabled”) status determines whether the data are loaded and can be plotted in the Display view. | YES | YES | ||||
Export | Mainly used to generate affine and splice tables as CSV files that can be uploaded to LIMS. | YES | YES | ||||
View | Brings up a modal window with the data in a grid. | YES | |||||
Import affine table | Import a previously saved affine table so it could be re-applied to the data. | YES | |||||
Import splice table | Import a previously saved splice table so it could be re-applied to the data. | YES | |||||
Import legacy affine table | Only used if you want to apply an old affine table to the currently imported data. (You would need to know the difference...) | YES | |||||
Import Section Summary Files(s) | Only used if section summaries are not automatically loaded from Correlation Downloader target directory, which is the standard procedure now! | YES |

3.3. Add new data (non-image data types)
...
- If no data exist yet in the Correlator database, the Data Manager window is empty except for the Root item.
- Right-click on Root to get the single item on the menu, Add new data (Fig. 3.2-3a1a).
Once the first If non-image data file has been importedexist in the directory, Correlator has created a directory with at least one Site folder.
Right-click on the top item on the menu, Add new data (Fig. 3.2-3b1b)
In either case, selecting Add new data opens a browser window (Fig. 3.3-1).
Browse
to the data files in your directory
- the path will stick for future imports and updates
.
Select a single file, or multiple files of the same data type (and the same format).
In the example in Fig. 3.3-4, magnetic susceptibility was selected for holes 1, the natural gamma ray data files for Holes 361-U1476A and 361-U1476B, B and D are selected.
The first 30 rows of data for each hole are displayed in the Generic Data tab (Fig. 3.3-52).
For commonly used data types, all column headers and column data should be automatically and correctly populated.
If that is not the case, you get a warning and must specify at least the Depth and the Data columns using the correct selection from the column header context menu.
Click the Import button at the bottom right and the focus returns to the Data Manager tab where a data summary line is added (Fig. 3.2-2).
Figure 3.3-41. The Import button opens in Generic Data window, where user may have to fill in the Data Type column by clicking on the header “Data Type” and selecting the appropriate item (in this case, Natural Gamma).
Figure 3.3-52. Upon importing data, line items for each data type and each hole are added in the Data Manager tab . Note the Saved Tables folder created for affine and splice tables later created. Also note the Section Summaries folder automatically created and populated with the section summaries from the LIMS registry (more on that below).
Special case: multiple files for the same data type
Correlator is trying to help you with file naming upon import. However, sometimes you may need to help Correlator learn the import data file, such as when you use correlation data from sources other than the JRSO Downloader app.
...
One of the primary objectives of stratigraphic correlation is to correlate section data from a new hole rapidly to the data from one or more previous holes to check if coring gaps in previous holes are recovered in the current hole. If coring gaps are not covered adequately due to the change in water depth (mostly due to tides, but also other environmental and operations factors), you want to provide relative coring offset (drill down interval) instructions to the drillers in near-real time.
