Hi everyone, I could solve this problem like this:
First: read the rows and columns of your raster map using r.info. Appropiate sample intervals are obtained by dividing that number by 100. For example, if you have: Rows: 7603 Columns: 8556 Good sample intervals are: 76,86 So, set up your region to match one of the raster maps that you are using (if you defined a group it can be any of the maps in the group), for this use g.region. Now you should be able to run i.cluster with the sample intervals = 76,86. Worked for me. Here you can find more info regarding this topic, it is very helpful even if you are ussing another version of GRASS: http://grass.osgeo.org/gdp/imagery/grass4_image_processing.pdf Best, Eliette -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Problem-with-i-cluster-tp3887750p4503475.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
