nv_super ? -f fixStructure -m movStructure ?

The super command calculates rms deviations between coordinates of currently stored structures. A matrix of rms values between all pairs of selected structures is reported. Only structures selected with "select" command, and atoms select with "match " command are used in the comparison. Without any options super does not actually change the coordinates of the structures. With the -f option, the structures are moved so as to minimize the rms deviation with the structure specified with the fixStructure parameter. By default, all structures are moved. The -m option can be used to restrict the command so that only the structure specified with the movStructure parameter is moved. For example, "super -f 1 -m 2" will superimpose structure 2 on structure 1."super -f 2" will superimpose all selected structures on structure 2.
