[Geraldo Deniro]

Hi GrADS Users,I made a script to make fortnightly anomaly of the mean sea level pressure daily data of R1, when i play this scripts on GrADS a message with error appears. Does anyone knows how to solve it or a easy way to make this script?
The error:
ga-> slp.gsNo hardcopy metafile openAll files closed; all defined objects released;All GrADS attributes have been reinitializedToo many contour levels -- adjusting cintga->
The script:
