The application menus are typically not needed. Here we present only Only the View menu as is shown here because it has a few low-level display options not available in the Display Preferences tab of the Display view (Fig. 2-45).

3. Manage data in Correlator
3.1. Prepare correlation data
Data directories
How you manage your data directory that Correlator is relatively flexible in terms of data file content and formats. Its import functions allow you to specify the only columns it really requires: depth and data. However, having the data files in a consistent format makes the process simpler and reliable. The following are the recommendations should be considered to be best practices on the JR.uses to import and update data is partly a function of your overall workflow and partly personal preference. The recommendation provided here is to keep site folders near the top of your directory, with each site folders having a data file for each data type and each hole, except for images, where the section half images are collected in hole folders (see example in Fig. 3-1). If working with JR data stored in the LIMS database:
- Download the non-image data using the Correlation Downloader app and place them directly in the site folder.
- The Correlation Downloader app has its own user guide, but one important feature is highlighted here: when you are correlation 'in real time', you will add data iteratively to the hole file for each core that is recovered and curated. Make sure you check the Append core check box.
- Download images using the LORE app and follow the current 'workaround' procedure:
- Batch-process the high-resolution, cropped JPG images with an R script (a
- Use the Correlator Downloader application to download data from the LIMS database. Refer to the separate user guide for that application.
- Create a folder for each site (example in Fig. 3.1-1).
- Download one file for each data type and hole into the site folder. Append data for each new core measured using the Append core feature in Correlator Downloader.
- Create an images folder in each site folder where you place all reduced section images for the hole.
- Batch-download the cropped section half images for a hole into a separate folder.
- Use the R script provided to crop and reduce the images, then move the reduced images to the images folder in the correlation data site folder.
- A separate user guide describes how to use the R script)
- Place the folder with the reduced images in the site folder.
If you have existing affine and splice tables for the site, place them in the site folder as well.
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.
Figure 3-2 shows the directory as Correlator presents it in the Data Manager view.
