What format do you use for binary data? Something tiled? I don't understand how you can read in a single column of a standard text or mmap-style binary file any more efficiently than by reading the whole file. -- Nathaniel _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
