hello, everyone.
i’m a new one of using knime, and i’m interesting in social computing and SNA.
so, is there any node about SNA? including the visualization of social graph?
Hi sizheng,
there is actually. In a recent project, a number of nodes where created that can build networks and enable you to play around with them.
For the visualization, connections with Cytoscape and visone are possible.
The plugin will be available soon, and I'll post the update site to this thread, once it is finished.
If you happen to be at the next Sunbelt conference there will be a tutorial on visone, including a section on Knime and the connection between both.
Great! i'm looking forward to them!
it's a pity i will not be at Sunbelt conference. Maybe i can get the tutorial from internet later?
it's released, you can now install the BisoNet plugin from the update site:

Hi uwe,
I'm also interested in the KNIME-Cytoscape connection that you mention. Unfortuntelly the link (http://tech.knime.org/update/bison) doesn't seem to be working any longer. I would appreciate if you could repost the link or update us on its future availability.
Thank you
Hi,
the link should be working fine, I just made an update to verify. What kind of error message do you get?
Hi Uwe,
The update site works initially but the installation fails with this error:
An error occurred while collecting items to be installed session context was:(profile=KNIMEProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Unable to read repository at http://tech.knime.org/update/bison/features/org.knime.features.bison.viz_2.2.2.0000874.jar.
I'm using Knime 2.3.1 on Windows XP.

Red out
Hi George,
I have just tryed to install the plugin my self and it worked just fine.
Could you please try it again after updating KNIME to the latest version 2.3.3. You can use the built-in update functionality available in the "File" menu to upgrade your version.
If the error message still occurs please try to open the update site http://tech.knime.org/update/bison in your browser. Besides other files the browser should display the features and plugins directory.
Thanks,
Tobias
Hi Tobias,
It worked for my new clean installation of Knime 2.3.3. Many thanks.
The plugin has a lot of nodes and I was wondering whether there is some sort of documentation (e.g. slides, workflows) illustrating the functionalities.

George
Hello again,
I am running KNIME 2.4 on Win XP. I tried to install the new Bisonet plugins but the Visualisation one gave me the following error.
Is there a way to fix this?

Please try to increase the memory in the knime.ini and check if this helps.
Thanks for this.

Do I need even more memory?

I just tried to install all Bisonet features into a vanilla KNIME 2.4 and it worked without any problems. Currently, I have no idea what the problem could be.
Hi Thor,
Thanks for the quick reply. Can I get a copy of the update site? This might solve the problem.
George
It seems that the signature jar file is corrupted and this might be because of our proxy server. A local update site could solve the problem.
George
Well I did have the same problem and found that REDUCING the memory size from xmx1024 to xmx512 solved the problem. One would assume KNIME was using up too much of the PC's memory and restricting it to 0.5Gb Maximum solved this and allowed the installation to proceed.
I've also found that "Viewer Windows" in KNIME are sometimes not displayed correctly with xmx1024m set, giving blank windows and black spaces in the window. Reducing the maximum memory size down resolves this issue too.
Simon.
It worked with Xmx512!!!
Simon, you're a star!
Many thanks,
George
