2. I found a typo in gaitanalysis/octave/2d_inverse_dynamics/leg2d.m where interp1 was called interp1q instead.

Now I’m getting the error:
/usr/local/lib/python2.7/site-packages/gaitanalysis/gait.pyc in inverse_dynamics_2d(self, left_leg_markers, right_leg_markers, left_leg_forces, right_leg_forces, body_mass, low_pass_cutoff)
240 angles, velocities, moments, forces =
241 octave.leg2d(time, marker_array, normalized_force_array,
--> 242 options)
243
244 dynamics = angles, velocities, moments, forces

ValueError: too many values to unpack

It seems leg2d.m only returns its first argument for some reason, the angles.
