Worst case you can always work around such issues with an extra layer of view manipulation: # create a raw view onto the contents of the file file_bytes = np.memmap(path, dtype=np.uint8, ...) # cut out any arbitrary number of bytes from the beginning and end data_bytes = file_bytes[...some slice expression...] # switch to viewing the bytes as the proper data type data = data_bytes.view(dtype=np.uint32) # proceed as before -n _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
