I'm new to GRASS and GIS environments in general, and I recently faced a problem when trying to get the profile plot from a DTM. When I draw the transect, instead of the plot, I get the following message:

Traceback (most recent call last):
  File "C:\Program Files (x86)\GRASS
6.4.2\etc\wxpython\gui_modules\profile.py", line 468, in
OnCreateProfile

self.DrawPlot()
  File "C:\Program Files (x86)\GRASS
6.4.2\etc\wxpython\gui_modules\profile.py", line 490, in
DrawPlot

marker=self.properties['marker']['type'])
  File "C:\Program Files (x86)\GRASS 6.4.2\Python27\lib
\site-packages\wx-2.8-msw-unicode\wx\lib\plot.py", line 342,

PolyPoints.__init__(self, points, attr)
  File "C:\Program Files (x86)\GRASS 6.4.2\Python27\lib
\site-packages\wx-2.8-msw-unicode\wx\lib\plot.py", line 145,
in __init__

self._points =
_Numeric.array(points).astype(_Numeric.Float64)
ValueError
:
could not convert string to float: *

Does anyone out there have an idea about my problem?

Please update to the latest GRASS GIS 6 version which should address this problem:
