New Revision: 26720
URL: http://svn.gna.org/viewcvs/relax?rev=26720&view=rev
Log:
Created two new frame order system tests for the free rotor pseudo-ellipse PDB
representation file.
This is the two PDB files from the frame_order.pdb_model user function. The
two new system tests
are Frame_order.test_pdb_model_pseudo_ellipse_free_rotor_z_axis and
Frame_order.test_pdb_model_pseudo_ellipse_free_rotor_xz_plane_tilt.
