Hello,
Thank for your replies and for your previous example.
I try to follow it. I succeed in preparing data (v.db.update, v.net, etc. ).
Moreover, i succeed in generating relevant isochrones map thanks to GUI
graphical interface. i paste below an SS :
<http://osgeo-org.1560.x6.nabble.com/file/n5200944/SS_isochrone.jpg>
Could you explain a bit more how you created these isochrones ?
But when i try to apply your v.isochrones command line :
<http://osgeo-org.1560.x6.nabble.com/file/n5200944/SS_command_line_v.jpg>
an error message appears. "method" and "cost_column" parameters do not
exist (regardless of the method used).

I'm working with grass 7.0 and i re-downloaded the v.isochrones extension
from the repository.
How do you download the extension ?
Could you use g.extension to remove the extension and then reinstall ?
Something like this:
g.extension v.isochrones op=remove -f
g.extension v.isochrones op=add
it seems i'm still working with the old version of the
extension because "method" and "cost_column" do not exist. I use the console
command via the GUI. i don't use the true GRASS7.0 COMMAND LINE because i
don't know where the path has to pointed to ?
Normally, just typing 'v.isochrones' should work. Which OS are you
working in ?
The "method" and
"cost_column" parameters do not exist too for the v.isochrones GUI
(graphical interface).
That just means that you are still not using the updated version.
Try to find out which v.isochrones command is being launched. In
GNU/Linux you can do this by typing "which v.isochrones" in the command
line. IIUC, 'where.exe' does something similar in MS Windows.
