WormBase has been updated to the WS150 release of the database. New data includes orthologous relationships identified by the InParanoid algorithm (see the vab-1 Gene Page for an example). We’ve also overhauled the display of RNAi experiments. WS150 is the 6th “frozen” reference release of WormBase. It will be available at ws150.wormbase.org within the next few days. We encourage all users conducting long-term bioinformatics analyses to use the most current referential release of the database
