Identify disconnected nodes

[johnsojp]

Hi everyone,
Is there a way to quickly determine if any subjects in my sample have disconnected nodes after thresholding, and if so, to get a count or at least identify which specific nodes are disconnected? For context, I’m using a weighted graph with positive edges only, so the only way I’d have a disconnected node is if it only had negative edge weights–this seems unlikely but I’d like to check so I can be certain.

Thank you!
