Start Blast2GO by Java Web Start

Please select the max. amount of system memory (RAM) you allow JAVA to use to improve the performance of Blast2GO:

Usage	Memory
for testing, teaching and small projects	250 MB
up to 15.000 sequences	500 MB
up to 30.000 sequences	1000 MB
up to 40.000 sequences	1500 MB
up to 60.000 sequences (only with 64 bit CPU)	2000 MB
up to 80.000 sequences (only with 64 bit CPU)	4000 MB

If you want to adjust the amount of memory individually please use the dynamic memory JNLP URL: http://www.blast2go.com/webstart/makeJnlp.php?mem=

Database settings for Blast2GO Basic

The database server is: publicdb.blast2go.com
The current public database is: b2g_aug12

Java Web Start System Requirements:

The minimum requirement to run Blast2GO via Java Web Start is a working Java installation (version > 1.5) (on Win,Linux,Mac etc.)
In case you do not have that already please install the actual Java Runtime Environment (JRE) from http://www.java.com/download

By Java Web Start Technology (TM) (which is included in JAVA) you will be provided with the latest Blast2GO update each time you start the application. If your browser hasn't been set up to run Java WebStart JNLP files, the link above will download a file called blast2go.jnlp. Some browsers will ask you what you want to do with the JNLP file (instead of automatically downloading it somewhere, or presenting it to you as text). If a dialog appears with “Open using application…” on it, use the javaws application to run your file (and check the box marked “Don't ask me again”):

Blast2GO Database Issues

(does not apply to the PRO version)

To connect to the B2G database you (your computer settings, your personal firewall) and your institute (institutes firewall, providers network settings) has to permit outgoing tcp connections on port 3306. Normally outgoing connections of this type are always permitted unless you have a highly restrictive network policy.

TIP: To easily test if B2G works fine press one of the green arrows in the B2G main frame, some GO graphs should appear more or less instantly. If you encounter problems connecting to the database please consult your system administer about your network settings (does not apply to the PRO version). If you problem persist please contact us so we can find a solution together.

Useful hints for Linux users:

On 64 bit Linux machines javaws is not available from Sun for the 64 bit bit jre package, so you need to install the generic JRE application.

Please check Java: “java -version” check/find Java Web Start: “whereis javaws” Run Java Web Start: “javaws -viewer” (in the Java Control Panel, under “Advanced”, set console to “show console”)

Start B2G from command line

 javaws http://www.blast2go.com/webstart/makeJnlp.php?mem=1024

Try the database connection from a Linux console

 mysql -hpublicdb.blast2go.com -ublast2go -pblast4it b2g_aug12

Set the right java version using “alternatives”:

 sudo update-alternatives --install "/usr/bin/javaws" "javaws" $(which javaws) 1

 sudo update-alternatives --set javaws $(which javaws)
