Here is another method if NCO doesn't get it done. This is a trick
to remove the "unlimited" characteristic on a named dimension. This
method is relatively slow, but it has the advantage of simplicity
and nothing new to install. This is in the general class of:
ncdump in.nc | user hack | ncgen -o out.nc
Here is a specific example to remove unlimited. Change the dim name
and integer value to match your file. C shell syntax:
set str1 = 'time = UNLIMITED ; // (24350 currently)'
set str2 = 'time = 24350 ;'
ncdump in.nc | sed -e "s#^.$str1# $str2#" | ncgen -o out.nc
By the way, the whole file must *always* be rewritten at least once
when changing "unlimited". Due to the internal structure of Netcdf
3 files, it is impossible to switch the unlimited characteristic on
or off in place.

has a record dimension to a file that contains no record dimension at all?
