[GRASS-user] sh: 1: v.net.components: not found

Gunnar_Oehmichen · October 24, 2013, 2:02pm

Dear GRASS user list,

While accessing GRASS via R i ran over the problem of missing a certain GRASS function: v.net.components
System:

Distributor ID: Ubuntu
Description: Ubuntu 12.04.3 LTS
Release: 12.04
Codename: precise

grass 6.4.1-1ubuntu2

Here is what i did in R (partly):

Created a stream network shape file via execGRASS( "v.net", ...)

and now I wanted to distinguish local stream networks:

execGRASS("v.net.components", flags="overwrite", parameters=list(input="Stream_known_Network",
+ output="Stream_known_connectivity", method="weak"))

Fehler in parseGRASS(cmd, legacyExec = legacyExec) : The command
v.net.components --interface-description
could not be run (127), and produced the error message:
sh: 1: v.net.components: not found

Then I looked wether v.net.components is installed,

dpkg -L grass|gedit

...
/usr/lib/grass64/bin/v.neighbors
/usr/lib/grass64/bin/v.net
/usr/lib/grass64/bin/v.net.alloc
/usr/lib/grass64/bin/v.net.iso
/usr/lib/grass64/bin/v.net.path
/usr/lib/grass64/bin/v.net.salesman
/usr/lib/grass64/bin/v.net.steiner
/usr/lib/grass64/bin/v.net.visibility
/usr/lib/grass64/bin/v.normal
...

And it seems like, it is not.

Is my version generally missing the function?

Some help would be very much appreciated,

Thanks very Much,

Gunnar

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

Hey Markus,

after searching a bit, it seems like no stable Version of GRASS >= 6.4.2
is available for 12.04. . I hope I have missed a repository. Any hints on that?

Thanks,

Gunnar
