Hi! I've setup a map of graph-tool users at: http://www.buddymapping.com/maps/graph-tool If you want, go to the link and add yourself. :-) Once it reaches a number > 3, I'll put it on the website.

I've just corrected the documentation. Thanks! Cheers, Tiago -- Tiago de Paula Peixoto <tiago(a)forked.de> 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0

Normalized betweenness centrality
by Rui Carvalho 25 Oct '07

25 Oct '07

Hi, I'm a bit confused with the definition of normalized betweenness centrality in the documentation: http://projects.forked.de/graph-tool/wiki/BetweennessCentrality#BetweennessC entrality Basically, I'm looking at Freedman, Sociometry 40 (1), 35-41 and at the boost graph library page: http://www.boost.org/libs/graph/doc/betweenness_centrality.html Both the paper and the boost web pages mention a normalization factor of (n-1)(n-2)/2. However the 1/2 factor seems to be missing from the graph-tool documentation -is this just a documentation typo? Cheers, Rui

I guess there were already some modifications made since you last cloned the tree. Cheers, Tiago -- Tiago de Paula Peixoto <tiago(a)forked.de> 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0

I mean, do I > need to type --disable-visibility somewhere? Yes, you have to do: $ make clean $ ./configure --disable-visibility $ make You don't need to run autogen.sh a second time. (It would also have worked if you passed --disable-visibility to autogen.sh). Cheers, Tiago -- Tiago de Paula Peixoto <tiago(a)forked.de> 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0

Maybe you don't have libtool installed? Try "apt-get install libtool", and see if it works.

"Makefile.in" should have been created by automake when you ran "autogen.sh"... Are there any other errors reported by "autogen.sh"? Are you sure you have automake installed? (with something like 'apt-get install automake') Cheers, Tiago -- Tiago de Paula Peixoto <tiago(a)forked.de> 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0

Perhaps you mean you can't find the "configure" script. Development code usually doesn't include that script, it instead includes a mechanism to generate it. Since that is the case with graph-tool, what you wold have to do once you clone the repository is run: $cd graph-tool/ $./autoconf [configure options you use, if any] and then $make Good luck! And tell us if that solves the problem :) []'s ale *~

central point dominance: filter not found error

Hi everybody, I do not understand how to use the --central-point-dominance. I have a small undirected graph (a chain) in a file grafo.dot graph G { 1 [VERTEX_BETWEENNESS="0"]; 2 [VERTEX_BETWEENNESS="0.285714"]; 3 [VERTEX_BETWEENNESS="0.47619"]; 4 [VERTEX_BETWEENNESS="0.571429"]; 5 [VERTEX_BETWEENNESS="0.571429"]; 6 [VERTEX_BETWEENNESS="0.47619"]; 7 [VERTEX_BETWEENNESS="0.285714"]; 8 [VERTEX_BETWEENNESS="0"]; 1--2 [EDGE_BETWEENNESS="0.333333"]; 2--3 [EDGE_BETWEENNESS="0.571429"]; 3--4 [EDGE_BETWEENNESS="0.714286"]; 4--5 [EDGE_BETWEENNESS="0.761905"]; 5--6 [EDGE_BETWEENNESS="0.714286"]; 6--7 [EDGE_BETWEENNESS="0.571429"]; 7--8 [EDGE_BETWEENNESS="0.333333"]; } The following command: $graph-tool --undirected --load grafo.dot --central-point-dominance="VERTEX_BETWEENNESS|-" >graph-tool error: graph filtering error: filter not found $graph-tool --undirected --load grafo.dot --central-point-dominance >Usage: /usr/local/bin/graph-tool [options] > >graph-tool: error: --central-point-dominance option requires an argument $graph-tool --version: >graph-tool 1.1.2 (r111) (configured with ./configure --disable-visibility) $gcc -v >gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4) $uname -r >2.6.20-16-386 Any suggestion?
