Hi ChenDongDong!



Your error message suggests that eofudf is not
properly registered as a UDF. Check if

ga-> q udft

returns something like



eofudf Args: 2 6 Exec: /climate4/chdd/GrADS/UDF/eofudf

If not, your environment variable GAUDFT is not
recognized by GrADS. Maybe you need to use
~/.profile instead of ~/.bash_profile on SGIs and you need to do

GAUDFT=/weather4/chdd/GrADS/udft
export GAUDFT

in your .profile for your local default shell? Sorry I never used
SGIs but a local sys admin should be able to help you set the
environment variables correctly.

I hope this helps!
