[gradsusr] Error using tcorr

[Zablone Owiti]

Hi Users,
I get the following error when I try to do correlation between station data 
and gridded SST (ERSST v3). The station data is in binary format and I read 
it via a ctl (I am able to plot the station data series in grads). I am 
unable to figure out the fix for the error. 

How can I fix the error?
 
ga-> d tcorr(data.1,sst.2,t=1,t=30)
TCORR:  dim = 3, start = 1, end = 30
Data Request Error: Invalid grid coordinates
  World coordinates convert to non-integer  grid coordinates
    Variable = data.1  Dimension = 3
Error from TCORR:  Error getting grids
Operation Error:  Error from tcorr function
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = tcorr(data.1,sst.2,t=1,t=30)
