Dear Arlindo,<br>
<br>
I really appreciate your advices on computing percentiles using PyGrads, but<br>
unfortunately I have problems. I tried to follow your approach: installed<br>
PyGrads and other modules and make examples using your script but I cannot<br>
export grads variable into Python:<br>
<br>
>>> xx=ga.exp('djfslp/100')<br>
Traceback (most recent call last):<br>
File "<stdin>", line 1, in <module><br>
File "/usr/lib/python2.5/site-packages/grads/ganum.py", line 80, in exp<br>
return self.expr(expr)<br>
File "/usr/lib/python2.5/site-packages/grads/ganum.py", line 380, in expr<br>
d = self.eval(expr)<br>
File "/usr/lib/python2.5/site-packages/grads/gacore.py", line 668, in eval<br>
got = self.Reader.readline()<br>
KeyboardInterrupt<br>
<br>
I haven't used python earlier probably I am doing something wrong ??<br>
I tried also the example with model.ctl file and ts - the result was similar.<br>
<br>
any idea what's wrong?<br></blockquote><div><br></div><div><br></div><div>Which version of GrADS/PyGrADS are you using? From the error message, it appears that it is using method "expr" to export the variable, something that requires grads v2.0.a3 (or a version of v1.9 not yet released.) If using v1.9.0-rc1, make sure the IPC extensions are included, read this <a href="http://opengrads.org/wiki/index.php?title=Python_Interface_to_GrADS">http://opengrads.org/wiki/index.php?title=Python_Interface_to_GrADS</a></div>
