Backtranslation Tool

Entelechon is proud to hereby present the next version of the popular Backtranslation Tool! Based on the very good feedback for the first version, we have made several improvements. These improvements cover the user interface, as well as the mechanics of the tool.

You can now enter sequence motives, which will be included in or excluded from the resulting optimal sequence. Moreover, we have added automatic optimization functionality for the codon usage table and have assembled a detailed online help.

Possible reasons why the tool is not working

• Your browser does not support Java: Some operating systems and browsers do not support Java - upon which the backtranslation tool is based - by default. For example, Windows XP does not always come with Java support on board. For some versions of Netscapce, Java support is optional as well. In such a case, you should download the Java plugin. To do so, please visit this website:

  www.java.com

• Java support is switched off in your browser, or a virus protection program has deactivated the execution of Java applets. We hereby explicitly emphasize that we do not think that Java applications such as the backtranslation tool pose a security risk. If Java support is deactivated or its execution is prevented, you have to change the respective settings. Please consult your system administrator on how to do this.

• Your system is behind a firewall, which prevents the download of Java applets. In this case, only your system administrator can reconfigure the firewall to allow access to Java applets. Most firewalls allow access to Java applets by default.
