Dear Oscar,

Following is full error message after I adjusted following Ulich's advice:

interp = interp1d(indices[not_nan], x[not_nan], kind = 'quadratic') 
File "/lustre/work/apps/python-2.7.1/lib/python2.7/site-packages/scipy/interpolate/interpolate.py", line 311, in __init__
     self._spline = splmake(x,oriented_y,order=order) 
  File "/lustre/work/apps/python-2.7.1/lib/python2.7/site-packages/scipy/interpolate/interpolate.py", line 809, in splmake
     coefs = func(xk, yk, order, conds, B) 
  File "/lustre/work/apps/python-2.7.1/lib/python2.7/site-packages/scipy/interpolate/interpolate.py", line 530, in _find_smoothest
     u,s,vh = np.dual.svd(B) 
  File "/lustre/work/apps/python-2.7.1/lib/python2.7/site-packages/scipy/linalg/decomp_svd.py", line 91, in svd
     full_matrices=full_matrices, overwrite_a = overwrite_a) 
MemoryError
