eofgrads (still doesn't work )

[Henrique Barbosa]

Dear Dongdong,
Try changing you udftable. It seems you don't have writepermission to the directory where eofudf tries to writeits output. I mean, I am also using this eofudf and I don'tget the same error message.
In my case, my:
unix> echo $GAUDFT/usr/local/grads-1.9b3/udf/udftunix> cat $GAUDFTeofudf 2 6 expr value value value value charsequential/usr/local/grads-1.9b3/udf/eofudfeofudf.ineofudf.out
As you can see, eventhou eofudf is installed (as root) ina system directoty, the name of the input and output filesin the udftable (eofudf.in and eofudf.out) are not givenabsolute path names....
Therefore, once you try to run the script eof.gs, theeofudf fortran program will try to create these files inthe current directory, which you will most likely havewrite access.
Cheers,Henrique
