   Parameters:
       group=nameA [required]
	   Name	of imagery group

       subgroup=name
	   Name	of imagery subgroup

       input=name[,name,...]
	   Name	of raster map(s) to include in group

       file=name
	   Input file with one raster map name per line

DESCRIPTION
       i.group allows the user to collect raster  map  layers  in  an  imagery
       group  by  assigning them to user-named subgroups or other groups. This
       enables the user	to run analyses	on any combination of the  raster  map
       layers  in  a group.  The user creates the groups and subgroups and se-
       lects the raster	map layers that	are to reside in them. Imagery	analy-
       sis  programs  like  g.gui.gcp, i.rectify, i.ortho.photo	and others ask
       the user	for the	name of	an imagery group whose data  are  to  be  ana-
       lyzed.  Imagery	analysis  programs like	i.cluster and i.maxlik ask the
       user for	the imagery group and imagery subgroup whose data  are	to  be
       analyzed.

NOTES
       The  i.group  options  are only available for imagery map layers	in the
       current LOCATION_NAME.

       Subgroup	names may not contain more than	12 characters.

   EXAMPLE
       This example runs in the	"landsat" mapset of the	North Carolina	sample
       dataset.	 The following command creates a group and subgroup containing
       only the	visible	light bands of Landsat-7:
       i.group group=vis_bands subgroup=vis_bands input=lsat7_2000_10,lsat7_2000_20,lsat7_2000_30
