Main  application


Correlator

Stratigraphic correlation of cores from multiple holes at a drill site, by

  • depth shifting cores using high-resolution core logging data
and constructing
  • to construct a core composite depth below sea floor (CCSF) depth scale
, and by
  • ;
  • splicing selected core intervals to construct the most complete stratigraphic representation possible at a site.

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.

Support applications for efficient workflow aboard the JOIDES Resolution (and related shorebased work)


Correlation Downloader

Download core logging data from the LIMS database

, with automatic addition of

for use in Correlator.

  • Automatically downloads relevant section summary data required
by Correlator, options
  • for accurate computations in Correlator.
  • Options to filter the data
, and a feature
  • for edges and outliers.
  • Feature to append new core data iteratively to hole files.

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.

LORE Reports for Stratigraphic Correlation


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

-download all cropped section-half images from a hole via LORE, then batch

-process the images

with IMG-REDUX R script, which crops

, cropping the peripheral ~1 cm from the images

, then reduces

and reducing the image to

<200

~200 kb,

ready for import in Correlator

suitable for Correlator.

Version 4.0 was released on 31 March 1 April 2022. It can be downloaded at<GitHub link>

https://github.com/corewall/correlator/releases/tag/4.0_r1

Some 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).
