## Functions

string | gtsam::findExampleDataFile (const std::string &name)
| Find the full path to an example dataset distributed with gtsam.
string | gtsam::createRewrittenFileName (const std::string &name)

template<typename T>
GTSAM_EXPORT std::map< size_t, T > | gtsam::parseVariables (const std::string &filename, size_t maxIndex=0)
| Parse variables in a line-based text format (like g2o) into a map.
template<typename T>

| save 2d graph
GraphAndValues | gtsam::readG2o (const std::string &g2oFile, const bool is3D=false, KernelFunctionType kernelFunctionType=KernelFunctionTypeNONE)
| This function parses a g2o file and stores the measurements into a NonlinearFactorGraph and the initial guess in a Values structure.
void | gtsam::writeG2o (const NonlinearFactorGraph &graph, const Values &estimate, const std::string &filename)
