2 years ago I remember this bug fixed in bnt-1.0.7 and you can use the following code. good luck.
function [x, y, h] = draw_graph(adj, labels, node_t, x, y, varargin)
% DRAW_LAYOUT Draws a layout for a graph
%
% [X, Y, H] = DRAW_LAYOUT(ADJ, <LABELS, ISBOX, X, Y>)
%
% Inputs :
% ADJ : Adjacency matrix (source, sink)
% LABELS : Cell array containing labels <Default : '1':'N'>
% ISBOX : 1 if node is a box, 0 if oval
