If you 'set x 36' and try again, it should be fine. </div><div>--Jennifer<br><blockquote type="cite"><p><br> Error ocurred at column 1<br>DISPLAY error: Invalid expression <br> Expression = w</p><p>Variable w is present in when I do a "q file" and I can plot the w field on an XY plane for any time, which means no problem with the field. </p><p>I had the same done for my coarser grid with no probelm where the coarser grid had 90x90 points.
