We are speaking of potentially several hundred files.  It's part of the 
scientific work of the user of the last nine years...  Part of the 
problem is, that his Python/Numeric installation is 32bit and he has the 
last 32bit computer in the department.  This installation doesn't work 
with a 64bit Linux even with all 32bit compatibility libraries 
installed.  :-]

Which conversion script do you mean?  I couldn't find any conversion 
script that works or comes close to working.
