[gradsusr] about the interpolation with regrid2 function problem

[dyjbean]

Hi,all
i wondering how I can use grads to regrid a 2.5*2.5 resolution data to a finer resolution data such as 0.375*0.375 resolutiong. 
I try to use regrid2:
ga-> define t2m=regrid2(tmp2m,0.375,0.375)
the output grid is UNIFORM lat/lon:
dx =  0.38 deg and dy =  0.38 deg
# points in i(lon) = 960  # points j(lat) = 481
lon extent =    0.00 to  359.63 lat extend = -90.00 to  90.00
regrid method is: box averaging
Warning: ieee_invalid is signaling
Warning: ieee_inexact is signaling
FORTRAN STOP
Error from regrid2: Invalid transfer file format
  File name: udf.regrid.gfo
Operation Error:  Error from regrid2 function
  Error ocurred at column 1
DEFINE error:  Invalid expression.

Any suggestion or help for the above problem will be welcoming.

thanks
