| Hi friends Iam naveen. Iam modelling a rna molecule using forward kinematics(DH parameters).Using bond lengths,bond angles and dihedrals iam calculating the position of atoms sucessfully in the local frame starting from any one atom as origin and aligning the first axis along the first bond axis and so on. But iam not able to convert it to the PDB coordinates.Iam using compound homogeneous transformations used in robotics to do this.My problem is how to convert from local atom positions to positions given in PDB(Protein data bank file).Please help me. |
