I think that you are setting up the anomalies correctly. However, you may have a problem with your NINO4 domain:<br>
> "define nino4=aave(sstanom,lon=-150,lon=160,lat=-5,lat=5)”<br>

<br>
In GrADS, longitudes need to be ascending.<br>
<br>
I think that you want to reverse your longitudes so you have<br>
<br>
"define nino4=aave(sstanom,lon=160,lon=-150,lat=-5,lat=5)” OR "define nino4=aave(sstanom,lon=160,lon=210,lat=-5,lat=5)”<br>
<br>

I use the following script for correlating El Nino 4 index with sea level pressure (Jan 1979 to Dec2014). Please confirm me the following command.<br>
