I want to mark certain locations (lat and long in a .txt file) on a world map with symbols. I am using the following code. But I am not getting the desired results. Can you please resolve this issue? * * * #!/bin/bash gmt begin world png gmt coast -Rg -JK180/22c -B45g30 -Gwheat -Slightblue -A1000 -Y7c gmt plot -C -Sci -Wfaint -hi1 world\_1.txt gmt end * * * world.txt contains longitude and latitude of marking. |77.50|8.20| |83.50|17.20| |71.50|20.20|| |80.50|20.20| ---

- `world.txt` has `|` as field separator. GMT does not recognize that. use space or comma. - In your script your file is named `world_1.txt`. Should it be `world.txt`? - No _size_ is given in `-Sci`. Try `-Sc.1c` - No CPT is given in `-C` - remove it. - `-hi1` means your input file has 1 header line (I think). Does it? If not, remove it. ---
