Please consider to use more recent approaches like i.segment, r.learn.ml (addon), v.class.mlR (addon) etc. You can find an overview here which we presented at FOSDEM earlier this year: GRASS GIS in the sky: GRASS GIS as high-performance remote sensing toolbox https://fosdem.org/2018/schedule/event/geo_grass/ Best Markus -- Markus Neteler, PhD http://www.mundialis.de - free data with free software http://grass.osgeo.org http://courses.neteler.org/blog _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
