graph-tool Digest, Vol 99, Issue 13

Hi Tiago and all

Thank you very much for adding this functionality to graph-tool, I could
use this for sure. The only problem is, that since you've sent this email,
I'm trying to recompile the newest version of graph-tool and after lots of
trouble I managed to get it compiled and working, (without sparsehash
unfortunately) (the bigges problems I faced with not enough memory, but
never mind), now I have the working graph-tool 2.16 and stil if I try to
call the:

planar_position = graph_tool.draw.planar_layout(Graph_of_the_knot, pos=None)

function it prints:

Traceback (most recent call last):
  File "./knot_representations.py", line 1947, in <module>
    Crossings_adjacency_matrix = CrossingsAdjacencyMatrix(Nr_of_crossings,
Nr_of_ropes, Starting_points, Rope_path_length, Crossings_chirality,
Connections_dict_inv, Connections_dict)
  File "./knot_representations.py", line 1526, in CrossingsAdjacencyMatrix
    planar_position = graph_tool.draw.planar_layout(Graph_of_the_knot,
pos=None)
AttributeError: 'module' object has no attribute 'planar_layout'

Am I doing something wrong, or I'm not using the right version?

I've downloaded graph-tool 2.16 from the site.

I would also like to ask something about the sfdp.layout in the draw tool.
Can I set the C parameter,

*C* : float (optional, default: 0.2) Relative strength of repulsive forces.

separately for some vertices? I assume that I can't, because it's not a
property map, but I thought I'll ask.
Thx

I've downloaded graph-tool 2.16 from the site.

This function has been implemented in the current development version
only. You have to download it and compile from the git repository.

It will be available in the next version (2.17).

I would also like to ask something about the sfdp.layout in the draw
tool. Can I set the C parameter,

*C* : float (optional, default: |0.2|) Relative strength of repulsive forces.

separately for some vertices? I assume that I can't, because it's not
a property map, but I thought I'll ask.

No, it is a global parameter.

Best,
Tiago
