Ok, thanks, will try. The previous problem with "disappearing" particles was, that normalization of NULL-vector in WM3 gives (0,0,0), but Eigen gives (nan,nan,nan). So I needed to add such check in yademath. I do not know, what implementation is more correct: WM3 or Eigen. ______________________________
