<br></div><div>I tried to use the command cssgrid to interpolate a station data set to regular grid. My data is 2d 18262*7981, and 7981 is the number of station. When I run the code, it shows this error message:</div><div>
<br></div><div>"CSSGRID - error -493, coordinates 493 and M coincide for some M > 493 >= 1 (coordinate numbering starting at 1).</div><div>Error number -493 returned from c_cssgridd</div><div>fatal:cssgrid: Error number -493.</div>
<div>fatal:["Execute.c":8567]:Execute: Error occurred at or near line 47 in file data_interpolation.ncl"</div><div>Would anyone please tell what this message means and how to fix it? Does it relate to the missing values? Thank you.</div>
