25 g_confrms computes the root mean square deviation (RMSD) of two
26 structures after LSQ fitting the second structure on the first one.
27 The two structures do NOT need to have the same number of atoms,
28 only the two index groups used for the fit need to be identical.
31 only matching atom names from the selected groups
32 will be used for the fit and RMSD calculation. This can be useful
33 when comparing mutants of a protein.
36 The superimposed structures are written to file. In a
39 the two structures will be written as separate models
45 calculated from the atomic MSD values can be written with
