Correlator | Stratigraphic correlation of cores from multiple holes at a drill site, by
Correlator can be used as a stand-alone application, but efficacy and support is maximized when it is used in conjunction with the SCORS support applications in the JRSO LIMS infrastructure. | Confluence wiki:

Support applications for efficient workflow aboard the JOIDES Resolution (and related shorebased work) | ||||
Correlation Downloader | Download core logging data from the LIMS database for use in Correlator.

MS Word:
| ||
LORE | Batch-download section half images for use in Correlator. Provide (A) lists of existing affine tables and splice interval tables, with links to uploaded user files; (B) detailed, LIMS-computed affine and splice interval tables; (C) CCSF (alternate) depths for any data set in the LIMS; and (D) data sets by selected splice. | |||
IMG_REDUX | Batch-process the images, cropping the peripheral ~1 cm from the images and reducing the image to ~200 kb, suitable for Correlator. | |||
SCORS Uploader and Manager | Load affine tables and splice interval tables created by an external application (e.g., Correlator) to the LIMS database where the information can be reported and applied to all data in LIMS. | |||

Some Miscellaneous notes:
- MacOS users need admin rights to be able to install the app.
- On the JR you don't need to download or install the application - ask JRSO personnel if the application
- As of April 2022, the application was running slow on the JR stratigraphic correlator machine.
- That computer is scheduled to be replace in August 2022.
- To improve performance a bit, click the Low resolution check box in the Get info window of the Correlator application before starting the program.
- Correlator installs a directory for its internal database at a default location that looks something like this:
- Documents [or other system folder] > Correlator > 4.0 > db | default.cfg | log | temp
- When you import correlation data from a directory of choice, Correlator indexes the data and places them in this directory for internal use.
- You don’t have to be aware of this directory but can change the path if needed (Fig. 1-2).

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).
