Output parameters created by program DYNAMICS

Parameter Meaning and data format
NOMOD List of residues in the NOMOD category (see Section 2.4), i.e. residues for which none of the models of local motion passed the goodness-of-fit test (χ2 too high), although at least one model provides a physically meaningful set of microdynamic parameters
EXCL List of residues that have been excluded by the program because none of the tested models of local motion are able to provide a physically meaningful set of microdynamic parameters (see Section 2.4)
RES The results of fit in the following format (array Nres × 10):
[Residue# τc S2 τloc Rex Sfast2 τfast model-Index χ2 CSA]
ERR The results of error analysis in the following format (array Nres × 7):
[Residue# δτc δS2 δτloc δRex δSfast2 δτfast]
RESERR Combined results of fit (RES) and error analysis (ERR) in the following format (array Nres × 16):
[Residue# τc δτc S2 δS2 τloc δτloc Rex δRex Sfast2 δSfast2 τfast δτfast model-Index χ2 CSA]
TAUCHI Record of all evaluations performed during the current DYNAMICS run in the isotropic tumbling mode or monomer-dimer equilibrium (empty if anisotropic tumbling). Each line is a summary statistics for all residues, in the following format:
τc, χ2(mod), Nnomod, χ2(nomod), runs, df, χ2(total), χ2(total)/df, Nexcl
ANISO Record of all evaluations performed during the current DYNAMICS run in the anisotropic mode (empty matrix in the isotropic or mono-dimer equilibrium). Each line is a summary of statistics for all residues, in the following format (for axially symmetric model):
τc, Dz/Dx,β,α, χ2(mod),Nnomod2(nomod), runs, df, χ2(total), χ2(total)/df, Nexcl In the case of fully anisotropic tumbling model, the format is τc, Dz/Dx, Dy/Dx β,α,γ χ2(mod),Nnomod2(nomod), runs, df, χ2(total), χ2(total)/df, Nexcl
runs This parameter counts how many times the selected model switches between model-free and “extended” model-free models in adjacent residues along the protein sequence
df Number of degrees of freedom, df = Ndat - Npar
chi2 Residuals of fit, χ2=freq[(R1expR1calcσR1)2+(R2expR2calcσR2)2+(NOEexpNOEcalcσNOE)2]
