Thanks for the follow-up Hamish. I am rather mystified by this problem myself as the rules file in '/usr/local/grass-xxx/etc/color/ryg' looks fine. The dataset that caused this mess ranges from 0.1 - 0.6. Other other color ramps appear to work fine. The resultant colr file had something like 0% 0:127:0 0:127:0 in it.. I can check again if that looks like it might mean something. dylan -- Dylan Beaudette Soils and Biogeochemistry Graduate Group University of California at Davis 530.754.7341 _______________________________________________ grass-dev mailing list [email protected] http://grass.itc.it/mailman/listinfo/grass-dev
