g.gui.iclass doesn't run after selecting training areas

[ThayseNery]

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()),
  File "C:\Program Files (x86)\GRASS GIS 7.0.1RC1\gui\wxpython\iclass\frame.py", line 513, in AddBands
    subgroup=self.g['subgroup'])

  File "C:\Program Files (x86)\GRASS GIS 7.0.1RC1\gui\wxpython\iscatt\controllers.py", line 164, in SetBands
    i = GetRasterInfo(b)

    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:

  ''File "C:\Program Files (x86)\GRASS GIS 7.0.1RC1\gui\wxpython\iclass\frame.py", line 911, in OnRunAnalysis

Process ended with non-zero return code 1. See errors in the (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.
