export a time series from GRADS

[Hai-Ru Chang]

Hello,
             I have a time series data file.  When I export  a  
variable from opengrads to python, I saw the following error.  The  
version of my opengrads is v2.0.a7.oga.3.  Dose anyone has a fix?   
Thanks!


 >>> temp = ga.exp('temp')
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "/home/hrc/install/lib64/python2.6/site-packages/grads/ 
ganum.py", line 119, in exp
     if nx==1: raise GrADSError, 'lon must be varying but got nx=1'
grads.gacore.GrADSError: 'lon must be varying but got nx=1'
