Thanks for your prompt reply. I tried NCOL format, it was still not working...
It works perfectly for me. I stored the snippet you sent in a file called test.ncol, then I did the following in R:
> library(igraph)
> g <- read.graph("test.ncol", format="ncol")
> g
Vertices: 10
Edges: 10
Directed: FALSE
Edges:
[0] DIP:2551N -- DIP:1189N
[1] DIP:2551N -- DIP:1330N
[2] DIP:2551N -- DIP:4449N
[3] DIP:2551N -- DIP:2425N
[4] DIP:1189N -- DIP:6289N
[5] DIP:6289N -- DIP:5008N
[6] DIP:6289N -- DIP:1361N
[7] DIP:6289N -- DIP:963N
[8] DIP:2425N -- DIP:6289N
[9] DIP:6289N -- DIP:2068N
> V(g)$name
