Dear Sir,

I am working on RegCM-4.1.1. I have to write single variable (e.g., 'u' ) in another file from given file containing all the variables. For this purpose, I am using 'cdo' commands 'selname' and 'delname' as cdo selname,u ifile ofile to write the desired variable. The results from ofile must be similar to the ifile, but after plotting in grads I have found there are differences in results from ofile to the results from the ifile.
 
Kindly help me in resolving this problem.
