You did

> 4. cp eofudf ~/GrADS/UDF

but specified

> /climate4/chdd/GrADS/UDF/eofudf

in your udft table.  Are ~/GrADS/UDF and
/climate4/chdd/GrADS/UDF/eofudf the same directories? They should.  Is
"export GAUDFT=/weather4/chdd/GrADS/udft" specifying the udft file you
created in ~/GrADS/? It should.

Some background and things to try:

Eof.gs creates a data file eof_in.gad and then calls eofudf.  Grads
itself will produce the eofudf.in file when  eof.gs  calls eofudf  via
"d eofudf(zprs,12,12,-1,70,zprs_)".  Both, "eofudf.in" and eof_in.gad
are needed by eofudf to compute the EOFs.  These files are supposed to
be created in the directory where you started GrADS because this is
where eofudf is looking for them.  Eofudf will then produce a GrADS
descriptor and binary file with the result of the eof analysis as well
as an eofudf.out file.  All these files are created in the current
directory.  Eofudf is passing the 1st EOF back to GrADS in eofudf.out
and  GrADS displays it.   For some reasons GrADS is correctly trying
to but fails execute eofudf reporting that
/climate4/chdd/GrADS/UDF/eofudf does not exist. This produces the
GrADS error line


sh: line 1: /climate4/chdd/GrADS/UDF/eofudf: No such file or directory

The next two lines


Error from eofudf: Error opening transfer file
  File name: eofudf.out

Are GrADS's complain that it didn't find an eofudf.out file to produce
a display.  Of course it couldn't as eofudf was never executed.

If both eof_in.gad and eofudf.in are created in your current
directory, you may try to execute eofudf outside of grads from the
command shell:

$ cd /the/directory/where/you/started/grads
$ /climate4/chdd/GrADS/UDF/eofudf

Please do so and report back the result.
