[gradsusr] Study area separated

[Hyacinth Nnamchi]

 Hi Serge,

My guess is that you have some extra one or two grid points on the LONGITUDE dimension. 

To get rid of it of this, you may have to re-write your data from the original file by explicitly setting out x and y.

Alternatively, let's say the data you using is 144*71 (lon*lat), the grid interval is 2.5 degree, and zero (0) is a grid point. You can do:

'set lon 0 357.5'   # This way you will have 144 longitude grids. I suppose you did 'set lon 0 360' before, which left you with 145 grid longitude points ! 

Good luck,

Hyacinth
