Hi Stephen,

A Tuesday 10 February 2009, Stephen Simmons escrigué:

You can always use ptrepack utility in PyTables to convert your existing 
PyTables files compressed with LZO to zlib, which is the standard 
compressor used by HDF5.  From that, you can reconvert them to LZF if 
this is your whish.
