GfactorsThe Gfactors option defines how the Gfactors for the mainchain bond lengths and angles are to be computed. The option is:
Gfactors  Y < Use Engh & Huber means for bond length/angle Gfactors(Y/N)?
Description:By default these Gfactors are computed using the Engh & Huber (1991) smallmolecule means and standard deviations. Where a structure has been refined using a different dictionary of values for these parameters it may appear to have very "unusual" geometry according to the PROCHECK Gfactors. Thus, if this option is set to N, the programs compute the Gfactors on the basis of the observed mean and standard deviation values in the given structure. This still allows any significant outliers to be highlighted despite a different dictionary having been used.
