I was able to make both vector and shaded plots from this file using
the attached ctl files. Your errors below suggest that the data you
are looking at have (perhaps) more than one missing value and/or
values with "NaN". I suspect you have a really large number
somewhere. If you try "set gxout grfill" instead, it might give you
a clue where the point is. If you did use the same file as
attached, something else is going on (maybe an endian problem?).<br>

I created descriptor files and able to open the file. Data
displays properly while <br>
using <b>gxout contour</b>. But is not properly displaying
while using <b>gxout vector</b><b><br>
</b>and<b> </b><b>gxout shaded. </b><br>
<br>
<br>
<br>
1) While trying to display data using 'gxout vector' command <br>
<br>
In addition to plotting vectors corresponding to the data values,
Long arrows <br>
originating from every missing value grid point and directed
towards left bottom<br>
corner of figure. <br>
<br>
How could this false arrows be removed? <br>
<br>
2) Also while trying to display data using 'gxout shaded' command
I got the following error<br>
<br>
---------------------------------------------------------------------------------<br>
ga-> set gxout shaded<br>
ga-> d uvel<br>
Contouring: -0.8 to 0.8 interval 0.2 <br>
Logic error 8 in gxshad<br>
Error in gxshad<br>
<br>
I searched GrADS archives and understood that '<b>Logic error 8
in gxshad</b>' <br>
is due to nan values in the data. But there I couldn't get any
solution to solve the problem. <br>
<br>
<br>
I am also attaching a sample data and control files I used to open
the file with this mail.<br>
<br>
<br>
I am using GrADS Version 2.0.a6<br>
<br>
<br>
Please give me some suggestions.<br>
<br>
<br>
<br>
Thanking You<br>
