[gradsusr] Error in Temporal Correlation

[Sourabh Shrivastava]

Dear Friends,

I am trying to calculate Temporal Correlation using GRADS.
My script is :

'reinit'
'open rf.25_1982_2014_jun.ctl'
'run rgbset.gs'
'set t 1 33'
'define rainclimate = ave(rain, t=1, t=33)'
'define anom = rain-rainclimate'
'define man = aave(anom, lon=74., lon=85., lat=18., lat=27.)'
'close 1'
*
'open sst_jun.ctl'
'define sstclimate = ave(sst,t=1,t=33)'
'set t 1 33'
'define anomsst = sst-sstclimate'
'define a = anomsst'
'set t 1'
'define corr = tcorr(man,a,t=1,t=33)'
'd corr'


and I am getting this error

Data Request Error: Invalid grid coordinates
  World coordinates convert to non-integer  grid coordinates
    Variable = man  Dimension = 3
Error from TCORR:  Error getting grids
Operation Error:  Error from tcorr function
  Error ocurred at column 1
DEFINE error:  Invalid expression.
Syntax Error:  Invalid Operand
  'corr' not a variable or function name
  Error ocurred at column 1

  Expression = corr



Thanking You
