is this possible ?
=20
Since I can show T2 graphically, I assume T2 is valid. So I tried 'q dims' =
to check I get.
=20
X is varying Lon =3D -100.923 to -95.6679 X =3D 0.999873 to 351
Y is varying Lat =3D 48.0392 to 50.9668 Y =3D 1.00022 to 196
Z is fixed
T is fixed=20
=20
This is my xdef and ydef from the control file
=20
xdef  351 linear -100.92260   0.01501352ydef  196 linear   48.03919   0.015=
01352
=20
Can anyone explain what the error/problem it might be ? And suggestions for=
 troubleshooting ?
Any help would be appreciated.

Thank you

Hi GrADs users,<BR>
&nbsp;<BR>
I am using pyGrADs and went through the examples adn tutorial and everythin=
g seems ok.<BR>
&nbsp;<BR>
&nbsp;<BR>
I can display variable&nbsp;T2 using my own data file on&nbsp;iPython&nbsp;=
using <BR>
&nbsp;<BR>
d T2<BR>
&nbsp;<BR>
However, when I try to extract from the data file using<BR>
&nbsp;<BR>
xx T2 <BR>
&nbsp;<BR>
I got an error,<BR>
&nbsp;<BR>
&lt;class 'grads.gacore.GrADSError'&gt;: 'invalid exchange metadata (idim,j=
dim)=3D(0,-2147483648) - make sure &lt;T2&gt; is valid and that lon/lat is =
varying<BR>
