Hi,
when chunking files with unlimited dimension, the unlimited dimension
must be given explicitly in nccopy, and will usually be set to one.
In a file with time as unlimited dimension, and X and Y as dimensions,
it is currently required to use
$ nccopy -k 4 -c "time/1,X/100,Y/100" in.nc out.nc
When running without time, it does not work:
$ nccopy -k 4 -c "X/100,Y/100" in.nc out.nc
NetCDF: Invalid argument
Location: file nccopy.c; line 637
Only for unlimited dimensions, one needs to give the dimension
explicitly, for all other dimensions a useful default (full dim-size) is
used. I think a useful default for unlimited dimensions is 1.
