Blast2GO Local Web Service

Blast2GO is an ALL in ONE tool for functional annotation of (novel) sequences and the analysis of annotation data. Running Blast2GO is easy, just follow these instructions.

Although the software runs on your computer it needs to connect to an external database and web service to function properly. The default settings are set to the database and web service hosted at Blast2GO. If you have a slow connection to this database it can affect the speed of mapping and annotation. An alternative is to have a local database installed to allow faster access. We have a local database and web service installed at CBIO and find that their is a significant improvement in the annotation and mapping process. Our services is publicly available so please feel free to use it!

The database settings can be changed within the Blast2GO application or within the "Blast2GO properties file" stored on your system. The settings for the web service can only be done in the "Blast2GO properties file".

The following settings need to be changed in the "Blast2GO properties file":

---------------------------------------------------------------------
// Conectivity to WebServices
Webservice.url=http://omweso.cbio.uct.ac.za:8180/b2gws_axis2

// GO and B2G-Mapping Database
Dbacces.dbhost=omweso.cbio.uct.ac.za
Dbacces.dbname=b2g
Dbacces.dbuser=blast2go
Dbacces.dbpasswd=blast4itza
---------------------------------------------------------------------

In Linux the property file will be in "/home/user/blast2go/blast2go.properties" and Windows in e.g. "c:\\Documents and Settings\user\blast2go\blast2go.properties"

Please consult the Blast2GO manual for detail instructions on how to use and configure the application.
