Hi,
I have been trying to apply supervised classification using
'''g.gui.iclass''' in GRASS GIS 7.0.1RC1 windows but it doesn't work
properly. What I do:
1) Launch g.gui.iclass
I can open the module by selecting group and imagery subgroup. But when
the windows GRASS Supervised Classification Tool opens, I observed that
name of imagery subgroup is missing. By adding it through select imagery
group I got the following error:
{{{
''File "C:\Program Files (x86)\GRASS GIS
7.0.1RC1\gui\wxpython\iclass\toolbars.py", line 163, in <lambda>
lambda event : self.parent.AddBands()),

7.0.1RC1\gui\wxpython\iclass\frame.py", line 513, in AddBands
subgroup=self.g['subgroup'])

raise GException("r.info failed:\n%s" % msg)
core.gcmd.GException: r.info failed:
Illegal filename <PERMANENT
>. Character not allowed.''
}}}
My file name doesn’t have any special character as it is called feb2014.
Although the imagery subgroup cannot been opened, I am able to:
2) Add RGB map layer
3) Add a class in the class manager and assign a custom color
5) I can digitize new area
But After selecting some training areas, I try to run the model and I got
another error:
{{{

output.''
}}}
I have been trying to work with this module for a week and I cannot figure
out why it doesn’t work.
Many thanks in advance for any help.
