Hi Katja, the error:
colvars: Too many iterations in routine jacobi.
is given by the function that computes the rotational alignment/fitting
onto a reference structure. It's very likely that one the RMSD restraints
in the colvars.conf file included in the tutorial is losing its structure.
Try looking at the trajectory in VMD and see what's going on. You may have
to make DCDfreq smaller to have the output written frequently.
