When I do "geng -help" the -n option is not documented. Why does geng accept it?
The following works perfectly:
geng 4 4:4 | showg

Subject: [Nauty-list] Issue with geng and showg
Hi there
I'm trying to use geng.c to generate and save my graphs. When I run
./geng -n 4 4:4 result.g6
I get
>A ./geng -d0D3 n=4 e=4
>Z 2 graphs generated in 0.00 sec
But, when I try to use showg to read my output, I get
./showg result.g6
>E showg: illegal character
It seems geng is not generating the graphs correctly. For the example above, I have
^D^@^@^@^@^@^@^@^@^@^@0^@^@^@^@^@^@^@^P^@^@^@^@^@^@^@�^@^@^@^@^@^@^@�^D^@^@^@^@^@^@^@^@^@^@0^@^@^@^@^@^@^@0^@$
which, compared to examples I found on internet, doesn't make sense at all.
Do you have some help to offer to me? I'm using Mac OS 10.6.7, gcc 4.2.1 and I have no experience with C. I want to generate the graphs and work with them in R.
Thanks
