NBS - Asymmetric network
Hi Team,

Does NBS support asymmetric networks? Is there any patch or upgrade available for download to support this feature?

Wam Regards

See attached for a directed version. This version does not have a GUI. You may need to adapt the code to suit your experimental design.

Thanks for the directed version of the NBS.

Will try it out and will get back to you if I have any questions.

Once again thanks.

Kind Regards

Hi,

Thanks for the code. As I was looking through the code I had a question.

The input to the function 'get components' is an adjacent matrix 'A' which seems to be symmetric. Does this make it 'undirected' or is it still 'directed'?

Kindly clarify. Thanks for your time and help

Warm Regards

The directed matrix is mapped to an undirected matrix for computation of connected components. The connected components are then mapped to directed subnetworks. So get_components operates on undirected matrices.
