回复： eof in grads

[dongdong]

Hi friends,
   I meet with the same problems when installing eofgrads in station. I did add eofudf entry and set GARDFT variable, what's the matter? I have been troubled for days, Can you help me? Thanks in advance!
  my steps are:

1. Our machine is SGI,so i download
eofgrads_sgi.tar.gz and unpack it at my home path

2. follow suggestions by the web
chdd at weather:~> pwd
/weather4/chdd/
chdd at weather:~> tar -zxvf eofgrads_sgi.tar.gz
chdd at weather:~> mkdir -p GrADS/GrADSscript
chdd at weather:~> cp eof.gs GrADS/GrADSscript
chdd at weather:~> mkdir -p GrADS/UDF
chdd at weather:~> cp eofudf GrADS/UDF
chdd at weather:~> vi GrADS/udft
eofudf 2 6 expr value value value value char
sequential
/climate4/chdd/GrADS/UDF/eofudf
/climate4/chdd/GrADS/UDF/eofudf.out
/climate4/chdd/GrADS/UDF/eofudf.in
chdd at weather:~> vi .bash_profile
export GASCRP=/weather4/chdd/GrADS/GrADSscript/
export GAUDFT=/weather4/chdd/GrADS/udft
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/lib

  After that, I did eof analysis in GrADS and it comes with a warning.

Dear Suha,

It's possible you didn't add the eofudf entry to your UDF table file (or
create that file if you didn't already have one) and/or you didn't set
environment variable GAUDFT to point to your UDF table file.  In Win2k,
you can set env vars from the Control Panel:
   Control Panel->System->Advanced
