CHRONOS CONOP9 Web Service

Introduction

CONOP9's primary purpose is to correlate stratigraphic sections which contain fossils. It finds the best sequence of first and last appearance of fossil taxa, can handle large amounts of data from many sections, and be used to construct a composite range chart for the taxa.


Background

CHRONOS has started work on a web services based version of the CONOP9 graphic correlation program. This system is still very much in its early stages and we are working with the CONOP9 author, Pete Sadler, to work out issues with this version. When the system is fully ready it will be announced, in the mean time, anyone is welcome to try out the interface. If you have comments, we would love to hear them, email them to systems at chronos.org. More information about the CONOP9 program and how it works can be found in the following PDF documents.

Test Data

To test the program out you will need input files. The zip file linked at the end of this paragraph will provide you with 4 example files (config, data, event and section) that you can use to test out the web service with. Download and unzip the file then launch the client program referenced in the next paragraph and use these files for the input.
testData.zip

Using the portal interface

To test run the Conop9 Portlet interface on this page simply download the testData.zip file located above and unzip it on your computer.  Next use the portal to load in the associated .dat .evt .cfg and .sct files and provide your email address.  You can then submit the run and your results will be emailed to you.  Note that this run only takes a few minutes to run, but some conop9 runs could take weeks even on large machines.  This is in fact what we are working on and more details will be coming shortly on how to construct your own runs and data sets and send them into this system.  Reading the background material provided above is an excellent starting point. 

Test Data Downloading and starting the program via webstart

CONOP9 web service reference client runs under the Java runtime environment (version 1.4) and is downloaded and launched from the CHRONOS web site via Java WebStart. With the initial download, the application is actually cached on your hard drive and run locally. Thereafter, you can run the program offline (without an Internet connection). However, if you are online when you start the program, WebStart will automatically check whether an updated version is available from the CHRONOS website.   Follow the sequence of events described out in the "Using the portal interface" above.
