BEL Navigator 1.1.0

[saqi...@gmail.com]

Hi, I downloaded BEL Navigator 1.1.0 from https://github.com/OpenBEL/bel-nav/releases and OpenBEL Framework 3.0.0

Then I started Cytoscape 3.2.1 and went to Apps -> AppManager -> Install from File 

I selected the belnav jar and installed

On the Apps pulldown in Cytoscape I can now see the BEL Navigator 

Then in Cytoscape I went to File->New->Network->From Knowledge Network

But now I get a popup entitled 'Task Error' saying "Cannot invoke method getRow() on null object”

And another popup saying "Load Knowledge Network for null" but nothing seems to happen after that;

Any ideas?

best regards

Hi Mansoor,

Here is a link to some older tutorials - they are not written for the BEL Navigator, but some of the general workflow concepts should apply - https://wiki.openbel.org/display/BEL/Training+Materials, specifically the KAM Navigator and the BEL Framework exercise tutorials.

A few questions - the following three steps are needed to successfully load a BEL network into the BEL Navigator

1. Have you compiled a KAM with the BEL framework?

2. After successfully compiling one or more KAMs, have you launched the BEL server (start-server.cmd)?

3. Have you configured the BEL Navigator App with the url for your BEL server?

Best,

Natalie

Hi - thanks for the link; 

Re. the other points, I have compiled a KAM with the BEL framework, and I did start the BEL server (start-server.sh) and configured the App with the URL for the server.

best regards
