Hi. I gridded some data using:

> gmt grdimage counts.xyz -R67.5/72.5/34/40 -t60

I want to draw an outline a frame outside the tile. I tried -T at the end

> gmt grdimage counts.xyz -R67.5/72.5/34/40 -t60 -T+o0.5p

GMT ERROR: grdimage [ERROR]: Unrecognized option -T

Someone know how to draw a frame outside the tile in GMT?

Thanks in advance

This is a new option in grdimage. You’ll need to build GMT from master version to access it.  
But you can try `grdvew` instead.

And do yourself a favor. Do not name grids with a `.xyz` extension. Let them be `.grd` or `.nc`
