Problems with regrid2 function

[Igor G ómez]

Hi all,

we are trying to regrid gfs data from 1 degree to 0.5 degree resolution.
We have found the regrid2 function, so we have installed it, and exported
the GAUDFT variable.

When we run this function in the way:

d regrid2(hgtprs,2.5,2.5,bs)

we recieve a following mistake message:

regrid requires 2 or more arguements:

Error from regrid2: Error reading from transfer file
  File name: udf.regrid.gfi
Operation Error:  Error from regrid2 function
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = regrid2(hgtprs,2.5,2.5,bs)

We have modified the source fortran code, for looking what the function
recieve. When we run another time the function, we obtein the next message:

d regrid2(hgtprs,2.5,2.5,bs)

arguments =   0.  NAN  21.  0.  1.  1.  NAN  0.  20.  1.  3.98991849E-34
  2384.  1.  0.  2.53635022E-43  5.04467447E-43  5.02870238E-34  1.40129846E-45
  NAN  1.12103877E-43
 number of arguments =  0


 regrid requires 2 or more arguements:

Error from regrid2: Error reading from transfer file
  File name: udf.regrid.gfi
Operation Error:  Error from regrid2 function
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = regrid2(hgtprs,2.5,2.5,bs)


Does anyone know what could be the problem?

Thak you in advance.
