Re: [Seqan-dev] Sparse property map

[Manuel Holtgrewe <manuel.holtgrewe@fu-berlin.de>]

John,

the long-term solution for us is to fix the map module and make the  
graph module work better with it.

A medium-term solution would be to fix graph_property.h.

The quick fix for you is to use std::map directly. Comment out the  
resizeVertexMap(). You can use seqan::_getId(vertexOrEdgeDescriptor)  
to get a number from a vertex or edge descriptor.

Bests,
Manuel
