 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\etc\python\grass\pydispatch\signal.py", line 229, in emit
     dispatcher.send(signal=self, *args, **kwargs)
   File "C:\Program Files (x86)\GRASS GIS

     **named
   File "C:\Program Files (x86)\GRASS GIS

     return receiver(*arguments, **named)
   File "C:\Program Files (x86)\GRASS GIS
 7.0.1RC1\gui\wxpython\iscatt\controllers.py", line 1111, in GroupSet
     self.scatt_mgr.SetBands(bands)
   File "C:\Program Files (x86)\GRASS GIS
 7.0.1RC1\gui\wxpython\iscatt\controllers.py", line 164, in SetBands
     i = GetRasterInfo(b)
   File "C:\Program Files (x86)\GRASS GIS
 7.0.1RC1\gui\wxpython\iscatt\iscatt_core.py", line 832, in GetRasterInfo
     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
     if self.RunAnalysis():

     returncode=returncode)
 grass.exceptions.CalledModuleError: Module run None ['r.info', '-gre',
 u'map=Feb2014_111_112_753mos at PERMANENT\r'] ended with error
 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.
