I've searched through the netcdf4-python trunk, but I find no reference of NetCDFFile as in how the basemap or Scientific.IO.NetCDF modules use it. For compatibility with my old scripts, is it safe to simply: from netCDF4 import Dataset as NetCDFFile ?? Thanks, john

What gave you the impression they did? There is a 'NetCDFFile' in function in basemap, but it is based on the pure-python netCDF module pupynere. It doesn't support netcdf-4 and I only recommend using it for the occasional light use. The netcdf4-python API is mostly compatible with Scientific.IO.NetCDF, so if you have old script that use the latter, you can try: from netCDF4 import Dataset as NetCDFFile The docs for netcdf4-python are at http://netcdf4-python.googlecode.com/svn/trunk/docs/netCDF4-module.html -Jeff
Thank you. I didn't think they used it, I just wanted to know if it was safe to do what you suggested to try. It does seem to work. Another question, can netcd4-python READ HDF files? Or is it just that it creates files that are readable? If it's the latter, does anyone have a suggestion for a python module that can read both hdf4 and hdf5?? Thank you, john PS: Jeff, this module seems to work very well! And I am very thankful for the introduction of compression.

Jeff,
I just built netcdf with the following script:
#!/bin/bash
./configure --enable-netcdf-4 --enable-hdf4 --enable-hdf4-file-tests
--enable-pnetcdf --enable-cxx-4 --with-hdf5=/flex_wrk/lib64
--enable-shared --prefix=/flex_wrk/lib64
make
make install
Everything seemed to work fine.
I then rebuilt netcdf4-python and got no errors.
IE:
export HDF5_DIR=/flex_wrk/lib64
export NETCDF4_DIR=/flex_wrk/lib64
python setup.py build
python setup.py install --prefix=/custom...
However, when I try to read a hdf4 file in Ipython I get:
In [1]: from netCDF4 import Dataset as NetCDFFile
In [2]: nci = NetCDFFile('scia_200910.hdf')
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call last)
/xnilu_wrk/flex_wrk/EMISSIONS/<ipython console> in <module>()
/xnilu_wrk/flex_wrk/bin64/site-packages/netCDF4.so in
netCDF4.Dataset.__init__ (netCDF4.c:6336)()
RuntimeError: Attempt to use feature that was not turned on when
netCDF was built.
What is it that I need to do to 'build' netCDF and netcdf4-python with
the support?
Thank you,
john

John: You forget --with-hdf4=<where hdf4 is installed>.
