Joe,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.ncHere 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.ncBy 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.

Does anyone know of a utility that will convert a large netCDF file that has a record dimension to a file that contains no record dimension at all?--Joe _______________________________________________ netcdfgroup mailing list netcdfgroup@xxxxxxxxxxxxxxxxFor list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/
