In my case, sometimes I wrongly write my data (using matlab) into grads format without replacing NaN with undefine value ( such as -1e13). Then got the same error message when shaded the figure.<br><br>I hope it helps.<br><br>Slovoed<br></div><div style="font-family: times new roman,new york,times,serif; font-size: 14pt;"><br><div style="font-family: arial,helvetica,sans-serif; font-size: 13px;"><font face="Tahoma" size="2"><hr size="1"><b><span style="font-weight: bold;">From:</span></b> Monica Ionita <Monica.Ionita@AWI.DE><br><b><span style="font-weight: bold;">To:</span></b> GRADSUSR@LIST.CINECA.IT<br><b><span style="font-weight: bold;">Sent:</span></b> Sunday, March
