PyAna - A Python module for ANA f0 file IO ========================================== This is PyAna, a Python module to perform file input and output operations with the ANA f0 file format, originally developed by Robert Shine. This module is mostly a wrapper around the slightly modified code of the IDL DLM library by Michiel van Noort. This library in turn borrows code from the old ANA routines. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Installation ============ This module can be installed using the standard NumPy distutils. Therefore, simply running python setup.py install will install this module to the default installation location. Running python setup.py will start an interactive installation process. Version history =============== 20090422, v0.4.0: * Fixed dimension problem, ANA and numpy expect dimensions in different order 20090422, v0.3.3: * Made errors a little nicer to read & more understandable. * Added pyana.writeto() wrapper for fzwrite, similar to pyfits. 20090331, v0.3.2: * Updated segfault fix in anadecrunch(). Illegal read beyond memory allocation can be as much as 4 bytes in the worst case in 32-bit decrunching (although this is rarely used). 20090327, v0.3.1: * Fixed a segfault error in anadecrunch(). Problem was pre-caching of a few bytes of compressed data, however the malloc() used for the compressed data did not have those few bytes extra, causing a 1 or 2 byte illegal read. Normally this shouldn't be a problem, but sometimes (like when I needed it) it is. 20090326, v0.3.0: * Old code had memory leaks, trying Michiel van Noort's improved code from libf0, the IDL DLM library. Hopefully this works better. * Renamed functions to correspond with the (original) IDL functions. load() -> fzread() and save() -> fzwrite(). Parameters still the same. 20090218, v0.2.2: * Added file exists check before calling _pyana.load C-routine
