The point is to get an array (xy) of shape (n_points x 2), see below. > I guess 'loadtxt' should be 'load'. After I changed this, another error > came.

Again, this could be an issue with your version of Numeric/Numarray/(old numpy). I dont know these old libraries well enough to say for sure. I think at least Numeric uses same type of broadcasting as numpy. So, what kind of numeric library are you using and what is the shape of xy after you have loaded the fixation-textfile?
