How to create a graph object with source and target vectors having zero labels?

Hi,

I am using a real network data from stanford SNAP webpage. Some of the nodes are labeled zeros, so I got the following error when I used graph

"Error using matlab.internal.graph.MLGraph

Source must be a dense double array of positive integer node indices."

I tried to attach the double vector but its size exceed 5 MB. Also, since this data consists of millions of nodes and links, how can I exrtact a portion of the network with couple of thousands nodes ?

Maybe run through all the nodes adding 1 to them?

Thanks Doctor. I added 1 to all of two million nodes not only to the ones with label 0, created and plotted the graph (attached).

I couldn't save the plot as a fig though.

Do you know how to extract any of the connected components (clusters) and exclude other clusters especially the isolated nodes?

Thanks

This category page lists the operations you can perform on graph and/or digraph objects (a few of the operations only make sense for undirected graphs and a few only for directed graphs.)

conncomp and biconncomp in the Analyze Structure section look relevant to your question.

Thanks Steven for referring me to conncomp documentation. I was able to preprocess my large graph and all is good now.
