Hi,
i have a  general question,
how can i do for exporting metric in tabular file using tulip ?

(i mean , degree distribution , betweeness ….)  after tulip generation data are available in the .tlp file
but i don't know how to export it into a text file using tulip gui .

cheers dave

Hi,

It is not possible directly with the GUI.
you can write an export plugin to do that or wait for the python script view that will be available soon (we just need to finish the packaging)

However it is a nice feature that we could add in the plug-in server (put a feature request for that if you want).

Wishes,
David.

Hi,

You will find in the post the source code of an export plugin that save all nodes/edges properties in a csv file.

CPP file:

#include "csvexport.h"

EXPORTPLUGIN(CsvExport, "CSV", "David Auber","18/01/2011","Alpha","0.1");

using namespace tlp;
using namespace std;

/*
const char * paramHelp = {
    // number of clusters
    HTML_HELP_OPEN() \
    HTML_HELP_DEF( "type", "unsigned int" ) \
    HTML_HELP_BODY() \
    "Determine the number of desired clusters, if 0 the algorithm will find determine the optimal number of clusters" \
     HTML_HELP_CLOSE(),
};
*/
//================================================================================
CsvExport::CsvExport(AlgorithmContext context):ExportModule(context) {
//    addParameter<unsigned int>("shifting", paramHelp, 0, false);
//    addParameter<DoubleProperty>("Edge weights", paramHelp, 0, false);
}
//================================================================================
CsvExport::~CsvExport() {
}
//================================================================================
bool CsvExport::exportGraph(std::ostream &os, Graph *g) {

    //nodes
    Iterator<string> *it(g->getProperties());
    os << "node_id";
    if (it->hasNext()) os << " ; ";
    while(it->hasNext()) {
       string str = it->next();
       os << str;
       if (it->hasNext()) os << " ; ";
    } delete it;
    os << endl;
    node n;
    forEach(n, g->getNodes()) {
        os << n;
        Iterator<string> *it(g->getProperties());
        if (it->hasNext()) os << " ; ";
        while(it->hasNext()) {
           string str = it->next();
           PropertyInterface *prop = g->getProperty(str);
           os << prop->getNodeStringValue(n);
           if (it->hasNext()) os << " ; ";
        } delete it;
        os << endl;
    }

    //edges
    it = g->getProperties();
    os << "src_id ; tgt_id";
    if (it->hasNext()) os << " ; ";
    while(it->hasNext()) {
       string str = it->next();
       os << str;
       if (it->hasNext()) os << " ; ";
    } delete it;
    os << endl;
    edge e;
    forEach(e, g->getEdges()) {
        os << g->source(e) << ";" << g->target(e);
        Iterator<string> *it(g->getProperties());
        if (it->hasNext()) os << " ; ";
        while(it->hasNext()) {
           string str = it->next();
           PropertyInterface *prop = g->getProperty(str);
           os << prop->getEdgeStringValue(e);
           if (it->hasNext()) os << " ; ";
        } delete it;
        os << endl;
    }

    return true;
}
