<div><strong>Hi Erick,</strong></div>
<div><strong></strong> </div>
<div>The script "grads_map.gs" will not correct the rotation as it is only used for the the display. To solve this problem you may first run "ppregrid". This script will be installed automatically in the system where you have installed PRECIS.
</div>
<div> </div>
<div>run it like</div>
<div> </div>
<div>ppregrid -d 0.5,0.5 filename.pp</div>
<div> </div>
<div>where 0.5 (in degrees) is the resolution (dx=50km, dy=50km).</div>
<div>After doing this your new file will be on regular grids and you do not need to run these grads scripts. </div>
<div>If you need to change pp format of that new file to display it in to Grads, do it in "xconv ".</div>
<div>Hope this will solve your problem.</div>
<div> </div>
<div>cheers</div>
