install eofgrads

[Dr. Parthasarathi Mukhopadhyay]

Hello Matias,
I was trying to use the EOF in a SGI machine after downloading the source code from your
website.
An error is occurring as follows
ga>eof u
      Writing data to transfer file...
      Executing eof binary ...

d eofudf(ue,19,12,-1, 70,ue_)
      EOFUDF Version 0.152
 Fatal ERROR in eofudf: (Error No.  -1 ).
 Error opening input transfer file
 STOP 1
Operation Error:  Error from eofudf function
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = eofudf(ue,19,12,-1,70,ue_)
   eof.gs: First call of eofudf returned Error. STOP

It looks to me that eofudf.in file is not getting created. I have given it in udft.txt
file.
can you suggest how the eofudf.in gets created?

Thanks in advance,
Parthasarathi
