• feature extraction in general. all that can be done using Numeric Python

which is a highly optimized package for number crunching tasks. that package is written in c and I wouldn't get it much faster if I wrote an external in c than just using numpy.

i see... i'm afraid there's no such connection in PD yet... this is planned to be integrated into a future version of vasp. Have you tried if the current vasp version can help you with your project?

haven't tried vasp yet. but it looks very interesting. i'll have a closer look at it. sven.
