Hello: I call the function as follows to input the gene interaction network,in which each row includes two genes interact with each other.
igraph_read_graph_ncol(&g,input,NULL,1,IGRAPH_ADD_WEIGHTS_NO,IGRAPH_UNDIRECT ED); According to the description in the documentation about the parameter "names"(I.e., Logical value, if TRUE the symbolic names of the vertices will be added to the graph as a vertex attribute called ³name²), the vertex should have an attribute named as "name" which are the gene symbols. And then I wanted to save the network into a file with gene symbols instead of ids. I called the function in the following way, but it did not save the gene symbols. igraph_write_graph_ncol(&g,output,"name",0); Do you have any suggestion? Thanks Best Quanwei
