Hello Binbin,

Without a copy of the input file (spcsref_2015082609f087) I can not recreate 
this problem, only make a guess as to what is happening.  Is it possible for 
you to upload this file to the GEMPAK support repository ( 
http://motherlode.ucar.edu/repository/alias/gempakuploads/ ) so I have a copy 
to work with?

As for the problem, I can only speculate until I have the file.  Is it possible 
that you have not sourced the GEMPAK envvars correctly?  Has your shell sourced 
Gemenviron or Gemeenviron.profile?  You can check this with the command 
"env|grep GEMPAK" - which will return a number of environmental variables if 
you have sourced the correct file.
