I did the relax with a model from Robetta Server using below command:
mpiexec -np 88 relax.mpi.linuxgccrelease \
-in:file:s robetta_model_1.pdb \
-relax:ramp_constraints false \
-relax:min_type lbfgs_armijo_nonmonotone \
-out:nstruct 86 \
-out:file:silent silent.out \
-out:file:silent_struct_type binary \
But, each output model was relaxed into the same scores or geometries.
I am not sure if I used the correct command or not.
Thank you so much for your help and advice,
