Corelyzer was built-in a simple interface to access online core image services like the IODP Janus database and IODP LIMS service to retrieve the high-resolution core section images.
In current version, Corelyzer supports 3 online core image services: JANUS database with CHRONOS service, IODP LIMS on-shore database and IODP LIMS on-ship database. For 2 IODP LIMS services, the query web service protocol was used to retrieve core image's metadata. Corelyzer uses the CHRONOS webservices capabilities to access JANUS and retrieve the URLs to the images. Corelyzer will rotate the images 90 degrees counter-clockwise, because all the IODP images are vertically oriented, where Corelyzer displays data horizontally. This plugin accuratly position the core sections using CHRONOS web service to access the curated length and top depth (mbsf) of each core section image.
The user interface has been designed in a stream-lined manner. To bring up the plugin select the menu item File->"Show IODP lists..."->"Image list from services" tab. Here are the steps to get image listing and load selected images:
Select which online service to use. Currently CHRONOS, on-shore LIMS and on-ship LIMS services are available.
Enter an IODP site to search for (e.g. site number 1215)
Click on the Search button. A listing of core section images should become available
You can optionally input the depth range to filter the returned available image section in the result table. Depth range should be input as string like "0-20", meaning only list image section of top depth from 0 meter to 20 meters (mbsf). The default value 0.0 will list all image sections returned by the online service.
Select the images to load
Click on the "Load selected image files" button
User must wait as image files are retrieved over the web, processed and displayed. A progress bar indicating the status will update during the process in the main window.
Each loaded image will be loaded and placed in the seesion and track named with the combination of "leg", "site", "hole" and "core" metadata information from the online core image server.
