Hi, off-liners. I have made some changes to the DKinFit code such that it now generates the 7x7 covariance matrix from the 5x5 tracking error matrix. The DKinFit code also restores the 5x1 state vector from the momentum and position vectors. Richard should be able to put the 5x5 matrix in the REST output instead of the 7x7 matrix. Simon
