<p>I followed with your suggestion and run the next check gs file:</p>
<p></p><div>'sdfopen d:/grads/mada/data.cdf'<br>'open d:/grads/mada/maskout_china.ctl'<br></div>'set lon 61.25 143.75'<br>'set lat -8.75 56.25'<div><br>'set lev 0 0'<br>
'set e 1 1'<br></div>'set t 114'<br>'d maskout(pdsi,1)'<br>; <br>It shows all the area instead of china. So I changed my gs file following your suggestion, but it showed some errors as below:<p></p>
<p>data request error: invalid grid coordinates</p>
<p>world coordinates convert to non-integer grid coordinates</p>
<p>variable=mask.2 dimension=3</p>
<p>operation errer: error from maskout function and aave function and tloop function</p>
<p>and so on...</p>
<p>then I checked mask.2:</p>
<p></p><div>'sdfopen d:/grads/mada/data.cdf'<br>'open d:/grads/mada/maskout_china.ctl'<br></div>'set lon 61.25 143.75'<br>'set lat -8.75 56.25'<div><br>'set lev 0 0'<br>
'set e 1 1'<br></div>'set t 114'<br>'d maskout(pdsi,mask.2)'<br>;<p></p>
<p>well, it also showed some errors:</p>
<p>data request error: invalid grid coordinates</p>
<p>world coordinates convert to non-integer grid coordinates</p>
<p>variable=mask.2 dimension=3</p>
<p>operation errer: error from maskout function </p>
<p>error ocurred at column 1</p>
<p>display error: invalid expression</p>
<p>expression= maskout(pdsi,mask.2)</p>
<p> </p>
<p>What's wrong with it? Does the ctl file I changed have some errors or other problems?</p><div>
<p>Thanks a lot! Best regards!</p>
