In this table, N is the number of couplings, N_PDB is the number of # molecular structures, and the columns are: # # D_OBS the observed coupling, Hz (also Dobs below). # DD the estimated uncertainty in the observed coupling, Hz. # W a weighting factor for computing RMS etc. # D the calculated coupling, Hz (also Dcalc below). # DI the dipolar interaction value, Hz. # # 2. The dipolar interaction value DI between atoms I and J is about # -21,585 Hz for an HN-N amide coupling, and is calculated as: # # (u0*hbar)*gammaI*gammaJ/(4*PI*PI*rIJ^3) # # where u0 is the magnetic permittivity of vacuum, hbar is Planck's # constant over 2*PI, gammaI and gammaJ are the magnetogyric ratios for # spins I and J, and rIJ is the distance between nuclei I and J. # # 3. For a coupling between atoms at coordinates (xI,yI,zI) and # (xJ,yJ,zJ) with distance rIJ, the direction cosines are expressed # as: xIJ = (xI-xJ)/rIJ, yIJ = (yI-yJ)/rIJ, and zIJ = (zI-zJ)/rIJ. # Then, with tensor values Da and Dr, then the rhombicity Rh = Dr/Da, # the generalized magnitude GMag = sqrt( 8.0*da*da + 6.0*dr*dr ), and # the dipolar coupling is calculated as: # # |DI|*(Da*(3.0*zIJ*zIJ - 1.0) + 1.5*Dr*(xIJ*xIJ - yIJ*yIJ)); # # 4. Q-factor, RMS, and Correlation factor are each computed from # couplings multiplied by W values from the table. For example, # for a collection of N couplings, the RMS is computed as # RMS = Sqrt( SumSq( W*Dobs - W*Dcalc )/N ). # # 5. For a collection of N couplings, the Q_FACTOR is computed as # Sqrt( SumSq( W*Dobs - W*Dcalc )/[N*(Da^2*(4 + 3Rh^2)/5)] ). # # 6. In fitting via SVD (saupe order matrix method) coupling values # are divided by uncertainty DD to determine the order matrix values. # So, in this case, the DD values will influence the tensor parameters # but the W values will only influence the reported statistics. # # 7. In non-linear fitting mode, the fit attempts to minimize the RMS, # which is weighted by the W values. So in this case, the DD values # will not influence the tensor parameters, but the W values will. # # 8. Methylene CH2 couplings, such as GLY HA#/CA, are given as the # sum of both H-C couplings. Likewise, methyl H-C couplings such # as ALA HB#/CB are given as the sum of three one-bond H-C values, # as in the full separation between the two outer peaks of a # methyl CH3 quartet. # # 9. All euler angles are given as an XYZ Rotation which rotates the # PDB file coordinates onto the alignment tensor frame. # # 10. For non-linear fitting, SAUPE (order matrix) values are # back-calculated from the fitted Da, Dr, and rotations. # The five values reported in the SAUPE line of the table # correspond to the five coefficients c1 ... c5 which define # the 3x3 order matrix S: # # Sxx = -1/2(c1 - c2) Syy = -1/2(c1 + c2) Szz = c1 # Sxy = Syz = c3 Sxz = Szx = c4 Syz = Szy = c5 # # 11. The three values reported in S_XYZ are the diagonal # elements of the diagonalized order matrix S, sorted so that # |Szz| > |Syy| > |Sxx| # # 12. Values for EULER_ANGLES are the XYZ rotations calculated from # the order matrix values.
