Hi all! As you know landsat data has separate files for different bands. Creating a subset is a wise option to work on region of our interest. Therefore, I used this method to subset my image - d.zoom || g.region g.region -p r.mapcalc *subset*=original as suggested in http://osgeo-org.1803224.n2.nabble.com/Raster-Map-subset-td4523291.html#a4526819 .
But with this I can subset one band data at a time. Is it somehow possible to use i.group and region definition to obtain subsets of all bands? Scripting might be an answer but I have no much idea about it. Thanks and regards, Chethan S.
