       group=name [required]
           Name of imagery group

           Name of imagery subgroup

           Name of raster map(s) to include in group

DESCRIPTION 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  selects the raster map layers that are to reside in them. Imagery analysis
       programs like g.gui.gcp, i.rectify, and others ask the user for the name  of
       an  imagery  group whose data are to be analyzed. Imagery analysis programs like i.cluster
       and i.maxlik ask the user for the imagery group and imagery subgroup whose data are to  be


       The   options  are  only  available  for  imagery  map  layers  in  the  current

       Subgroup names may not contain more than 12 characters.

       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: group=vis_bands subgroup=vis_bands input=lsat7_2000_10,lsat7_2000_20,lsat7_2000_30
