Hello, I want to use the global Bouguer anomalies model WGM2012 available at BGI site (http://bgi.obs-mip.fr/fr/data-products/Grids-and-models/wgm2012) with GMT5.1.0 for the Hawaii-Emperor islands. Then, I want to extract the region -R150/220/0/60 from the grid file. So I write : gmt grdgradient $grid -R150/220/0/60 -A270 -GBouguer_intens.grd -Ne0.6 where $grid calls WGM2012_Bouguer_ponc_2min.grd But the output image shows data only between 150°W and 180°, as if grdgradient could not pass from -180/180 to 0/360 longitudes data. Without -R specification, the map is correct (but the running time is delayed) ! I don’t understand... My script is attached below.
