摘要：We present the status of runs performed in the twisted mass formalism with Nf =2+1+1 flavours
of dynamical fermions: a degenerate light doublet and a mass split heavy doublet. The procedure
for tuning to maximal twist will be described as well as the current status of the runs using both
thin and stout links. Preliminary results for a few observables obtained on ensembles at maximal
twist will be given. Finally, a reweighting procedure to tune to maximal twist will be described.
