You would need to update to at least the next dot release: 6.4.2 (bettet 6.4.3): http://trac.osgeo.org/grass/wiki/Release/6.4.2-News#Newmodules " New modules i.topo.corr - Computes topographic correction of reflectance in satellite imagery m.nviz.image - Creates a 3D rendering of GIS data (renamed from nviz_cmd) v.net.allpairs - Computes the shortest path between all pairs of nodes in the network v.net.bridge - Computes bridges and articulation points in the network v.net.centrality - Computes degree, centrality, betweeness, closeness and eigenvector centrality measures in the network v.net.components - Computes strongly and weakly connected components in the network v.net.connectivity - Computes vertex connectivity between two sets of nodes in the network v.net.distance - Computes shortest distance via the network between the given sets of features v.net.flow - Computes the maximum flow between two sets of nodes in the network v.net.spanningtree - Computes minimum spanning tree for the network v.net.timetable - Finds shortest path using timetables " It has been added to a newer release of GRASS 6 than you have currently installed. For ubuntu packages, see http://grass.osgeo.org/download/software/linux/ Hope this helps, Markus _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
