The current version of the Ranker program (v1.2) for Babase was developed by Karl O. Pinc. It consists of minor changes amd a major bug fix to the version developed by Jun Yang. This version was based on an earlier version developed by Jun Yang and Tyler J. Brock from Fall 2006 to Spring 2007. It was Tyler's Graduation with Distinction project when he graduated from Duke University in 2007. Tyler's thesis has been attached to this page and includes visuals of the program as well as conceptual visuals describing how the program works. It is a PDF file; use Acrobat Reader to view it.

The focus of Tyler's thesis was how to rank automatically; however, for stability reasons, this functionality is not in the current version of the Ranker. However, we plan to include this functionality in the next version of the Ranker.

Prerequisites to Running the Ranker

Running the Ranker

Software Development for Ranker

This section is currently under development.

The Ranker code currently resides under ~junyang/ranker/ on papio.biology.duke.edu. It should be managed by a source control system eventually.

Development Environment

You will need the following environment in order to be able to make changes to the ranker code:

Sign the JAR file

See instructions in signature/README.txt in the ranker development directory on papio. The signed JAR file can now be copied under install/, a symbolic link to the installation directory on papio. Note that all third-party jars must be signed by the same certificate as well, as per Java security policy. The Makefile does all these automatically.

Command line execution

From /var/www/html/ranker/ run:

java -cp ranker.jar:lib/jcalendar-1.3.2.jar:lib/postgresql-8.2-506.jdbc3.jar:lib/TableLayout.jar babase.ranker.Main
