Using NetCDF files for your data
Introduction
Software Installation
On Ubuntu
The Ubuntu package manager makes this very easy. Go to System->Administration->Synaptic Package Manager (you will need to enter your password) and select the packages:
- python-scientific (this provides a python interface for reading/writing NetCDF files)
along with:
- python-tk
- python-matplotlib) (these provide a means to view your data graphically)
Compiling from Source
This is not as convenient as using a package manager and is a bit messy!
Compiling the NetCDF Libraries from Unidata
The source code can be downloaded from Unidata:
wget http://www.unidata.ucar.edu/downloads/netcdf/ftp/netcdf-4.0.tar.gz
Now, unpack the tarball and build the libraries:
tar -xzf netcdf-4.0.tar.gz cd netcdf-4.0 ./configure --prefix=/opt/netcdf/netcdf-4.0 --enable-shared FC=ifort CC=gcc CXX=g++ CPPFLAGS="-DpgiFortran" \ FCFLAGS="-fpic" CFLAGS="-fPIC" CXXFLAGS="-fPIC" make make check make install
Note that we need to build the shared libraries. Hence the addition of the -fPIC flags
Installing the Python Interface
wget http://sourcesup.cru.fr/frs/download.php/1833/Numeric-23.8.2.tar.gz tar -xzf ... cd Numeric... python setup.py install
wget http://sourcesup.cru.fr/frs/download.php/2309/ScientificPython-2.8.tar.gz cd .. tar ...
but now need to hack setup.py for:
- netcdf path
- problems with /usr/lib and /usr/lib64
perhaps easiest to just patch with a symbolic link:
cd /usr/lib/python2.4/site-packages ln -s /usr/lib64/python2.4/site-packages/Scientific
