1- Is there a neat way of reading a METIS file with .graph extension as in http://www.cc.gatech.edu/dimacs10/archive/clustering.shtml data sets using igraph?
No, as far as I know -- you'll need to convert the file manually into something that igraph can digest.
vertices for all vertices starting from 1 to the number of vertices. I could not construct an igraph graph from this list. graph.adj.list() function does not work with such type of adjacency lists?
It should work, but note that the list is expected to be 0-indexed, i.e. neighboring vertices should be numbered from 0 and not 1. What is the error message that you see?
