Hi All
I want to show you the grid and data information of my data for  
helping  you to figure out my problem.

yes? use eof_time.nc
yes? use sst.nc
yes? show data
     currently SET data sets:
    1> ./eof_time.nc
 name     title                             I         J

1:1       1:1200

    2> ./sst.nc  (default)

yes? go regresst
... Linear Regression Along the T Axis
... Instructions:
Use the LET command to define new variables
Define the variable P as your independent (X) variable
Define the variable Q as your   dependent (Y) variable
Results will be variables "SLOPE", "INTERCEP" and "RSQUARE"
QHAT will be the regression estimate
Note: If "T" is your independent variable then
...   "SET GRID Q" after defining Q.

 **ERROR: illegal limits: P is not in the range X=109:291
