I cannot assess the complexity of the code regarding Numeric/numpy, as I don't use Python myself. I will forward these informations to the user in question and hopefully he can manage to convert his files. I'm afraid that will be a lot of files (he is using Numeric since many, many years and never updated to newer packages) > Also I would suggest that you have a Numeric/numarray working with some > older version of Python.

It's the installation I want to get rid of...:-) Thanks a lot frank _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
