Wendi,<br>You need to run those two define commands at the top of my previous email before attempting to define the xdist and ydist fields.� Also, since I can see your control file information, I can see that dlon is 0.004492369 and dlat is� 0.004522556.� So substitute those two values into your expressions for xdist and ydist also.<br>

<br>They define grid increments in terms of spatial distance rather than geographic distance.� If you're trying to change the axes and tick marks, you'll have to define an origin and define your x and y distances based on that.� For instance, if you set your lower left domain corner (latitude 0 and longitude 100), then you can define your coordinate distances using<br>
