-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2010-15610 2010-10-02 01:09:46 --------------------------------------------------------------------------------
Name : nco Product : Fedora 14 Version : 4.0.4 Release : 1.fc14 URL : http://nco.sourceforge.net/ Summary : Suite of programs for manipulating NetCDF/HDF4 files Description : The netCDF Operators, NCO, are a suite of command line programs known as operators. The operators facilitate manipulation and analysis of self-describing data stored in the freely available netCDF and HDF formats (http://www.unidata.ucar.edu/packages/netcdf and http://hdf.ncsa.uiuc.edu, respectively). Each NCO operator (e.g., ncks) takes netCDF or HDF input file(s), performs an operation (e.g., averaging, hyperslabbing, or renaming), and outputs a processed netCDF file. Although most users of netCDF and HDF data are involved in scientific research, these data formats, and thus NCO, are generic and are equally useful in fields from agriculture to zoology. The NCO User's Guide illustrates NCO use with examples from the field of climate modeling and analysis. The NCO homepage is http://nco.sourceforge.net/. -------------------------------------------------------------------------------- Update Information: A. Chunking supported in all operators. The exception is ncap2, which propagates chunking from fixed and copied variables, though not through algebraic expressions. (This capability may be in the next version.) http://nco.sf.net/nco.html#cnk B. ncecat, and all other operators, now retain the input deflation level, if any, for a variable, as the default for the output file. C. Deflation level (--dfl_lvl) propagates into ncap2 derived variables Thanks to Henry Butowsky. D. ncks -m now always summarizes metadata on chunking, compression, and packing Moreover, it prints metadata with clearer English descriptions E. ncpdq no longer packs grid properties such as coordinate variables, CF "special variables, or weights. Rationale: Coordinate variables are 1D, so packing saves little space, and the resulting files are difficult for humans to read. Similarly, Gaussian and area weights are often used to multiply other variables in re-inflated (unpacked) files. Packing such weights causes a considerable loss of precision in the result. If users wish to pack such variables, we could implement new packing policies that explicitly packs coordinates and weighting variables. We welcome your feedback. A workaround for those needing to pack such variables now, is to use the packing functions in ncap2, or to rename the grid properties prior to calling ncpdq. F. Stricter checks to identify malformed user-input strings. Issue more informative warnings, hints, and errors when detected. G. Prior versions of ncrename -a .old_nm,new_nm in.nc out.nc would, if old_nm did not exist, write the correct file then exit with an error message although no error had occurred. http://nco.sf.net#bug_ncrename_dot -------------------------------------------------------------------------------- This update can be installed with the "yum" update program. Use su -c 'yum update nco' at the command line. For more information, refer to "Managing Software with yum", available at http://docs.fedoraproject.org/yum/. All packages are signed with the Fedora Project GPG key.
