Is it normal that the translation parameters are set to zero?

parameter = [0, 0, angle(finalAngleID)+parameter(1,3)];

Bootstrapping with symmetry (one2all_symmetric.m) does not seem to refine the translational alignment of the particles.
However, changing this line to "parameter = [parameter(1,1), parameter(1,2), angle(finalAngleID)+parameter(1,3)];" to include translation makes some particles completely misaligned
