    Method RDC directed fragment assembly
    Details RDCs were used in the initial assembly of 6 fragments. RDCs from two media were used to set relative orientation of fragments. Translational relationships of fragments were dictated by sequence connectivities. The assembled structure was minimized using a molecular force field and RDC error function. All sidechain atoms beyond CB are missing.
