Pipe the result of cdo select
Added by David Wang over 11 years ago
cdo select takes arbitrary number of input files, which is great. However, I'm not able to pipe the result to another operator, such as
cdo ymonmean -select,year=1970/1999 $ifiles $ofile
gives the following message:
Error (cdo ymonmean) : Too many streams! Operator needs 1 input and 1 output streams.
Does cdo select returns one input stream, or am I mistaken?

All operators with an arbitrary number of input streams (ifiles) can't be combined with other operators if these operators are used with more than one input stream. Here is an incomplete list of these operators:
copy, cat, merge, mergetime, select, ens<STAT >If the input stream names have the same structure than you can try to use wildcards (? and *) to generate only one input stream name. In this case you have to use single quotes around the input stream argument. Here is an example:
cdo ymonmean -select,year=1970/1999 ifile1 ifile2 ifile3 ofile <-- error cdo ymonmean -select,year=1970/1999 'ifile?' ofile <-- worksThis feature is available since CDO version 1.5.9.

Thanks. It works like a charm.
