[GRASS-user] i.spectral.py in WinGrass

You are right Glynn, I just checked i.spectral.py and it has the
d.linegraph feature but, i.spectral is greyed out in wxpython gui and,
when I try to run it from the command line (using Msys wingrass7svn),
if I input a raster group I get the error:

GRASS 7.0.svn> i.spectral.py group=alos.radiance coords=720560,261787
< foi inesperado neste momento.
Traceback (most recent call last):
  File "c:/GRASS-70-SVN/scripts/i.spectral.py", line 236, in <module>
  File "c:/GRASS-70-SVN/scripts/i.spectral.py", line 231, in main

    for j, val in enumerate(what[0][3:]):
IndexError: list index out of range
GRASS 7.0.svn>

If I try to run it using the raster options I don't get any errors but
nothing is displayed to the screen.

Running from the command console in wxgui I get:

self._parser.Parse("", 1) # end of data

It looks as though I don't have the collections module?

Thanks for all the help
