System Requirements

A user needs to register to obtain a user ID before using this program. A web browser with JavaScript and cookie support is also required. To upload big files, JMaster's "JumpLoader" might be helpful. As a Java applet, JumpLoader requires the browser's support for Java.
As our main web browser used for testing/debugging, Mozilla Firefox is strongly recommended for users to explore WebArray/WebArrayDB. We also tested the program with Opera, Flock, Microsoft Internet Explorer (IE), and Google Chrome.

4. News
2008/3/17WebArrayDB (in BETA testing) - a cross-platform database system and analysis platform was integrated in. Any feedback is highly appreciated.
2007/08/18Microarray databases (WebArrayDB) were designed and are on testing.
2006/10/19R was upgraded to version 2.4.0. Accordingly Bioconductor was upgraded to version 1.9. More Affymetrix GeneChip types are supported.
2006/10/19The interface between python and R language was switch from Rpy to pipe offered by python. This permits R to run faster.
