The primary computer used for stratigraphic correlation on the JOIDES Resolution (JR) is the Apple computer with two large screens located next the NGR and Core Splitting Room. You can also run Correlator from other Macs or PCs. For this quick guide, the assumption is you are using CorrelatorMac_2.1_rc2.app or a similar version.
Get data for Correlator by using Correlator Downloader program called corrdownloader.jnpl. This is a Java program usually located on the Desktop or on the Mac's Dock bar (look for the Coffee icon).
CorrelatorDownloader is fairly straightforward to use. Select the data you want to download, cull the data if you want by limiting max for min values or trimming data near edges of sections. You can download multiple data sets from all the holes at a site, rather than doing each one separately (Figure 1).
- Press the bar at the bottom of the page called "Download correlation data".
- Download data to a folder of your choice. Lets use the Desktop and create a folder called ExpXXX-Correlator, where XXX is your expedition number.
You can hit the "Save control file" to reuse the corrdownloader.jnpl query later. For example, when more data are collected and you need to update the data you are using in Correlator. The query will be saved as a *.jsn file, which can be opened and reused by clicking on the "Browse" and "Upload" buttons in corrdownloader.jnpl.
A movie is available that shows how to get data: 1_LIMS2Correlator_INTRO.mov
