Best, J. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Tamas Nepusz Sent: Thursday, March 3, 2016 9:46 AM To: Help for igraph users <[email protected]> Subject: Re: [igraph] DL graph.read Error Msg Most likely the last line of the file does not have a newline character at the end. I'm not sure whether this is a bug (i.e. what the DL format specification says about trailing newlines), but you can fix the issue by adding a newline to the end of the file. T.
