hello everyone I’m trying to plot a grid to visualize the topography on my map with grdimage but I get an error and I don’t know what I’m doing wrong. I leave my script. I hope someone can help me … thank you very much in advance. the grid I’m using is GMRTv3\_9\_20210610topo.grd and I download it from [GMRT MapTool](https://www.gmrt.org/GMRTMapTool/) Juan.[scriptplot.sh.zip](https://forum.generic-mapping-tools.org/uploads/short-url/z1PKudZp1aeERtXtEy6RHCyaaKW.zip) (728 Bytes) ---
