Hi
Well I'm not sure that you can. But you can use the PT_IN_POLY function to mask the region, and save the result: yes? let xp = {83,91,88.8,80.2,83} yes? let yp = {10.8,17.07,21,14.8,10.8} yes? use etopo60 yes? let/Title="my_var" my_var = if pt_in_poly(rose,xp, yp) gt 0 then rose yes? Save /File=my_file.nc my_var In a second step you can save the surrounding region of interest in another file (I don't know why I can't do it in one step): yes? use my_file.nc yes? save /File=my_file2.nc /X=78:94 /Y=10:22 my_var Bruno On 10/18/2016 11:29 AM, Manche Shivashankar wrote:
