Formula for the calculation of RMSD

RMSD formula	Symbol	Explanation
$\mathbf{R}\mathbf{M}\mathbf{S}\mathbf{D}\mathbf{x}=\frac{1}{\mathit{N}}{\sum }_{\mathit{i}=0}^{\mathit{N}}\{\left[{{\mathit{r}}^{{}^{\mathbf{\prime }}}}_{\mathit{i}},\left(\mathit{t},\mathit{x}\right)\right]-{[\mathit{r}}_{\mathit{i}}({\mathit{t}}_{\mathit{r}\mathit{e}\mathit{f}})]{\}}^2$	N	No. of atoms in the selection of atoms
	$t_{\mathit{ref}}$	Reference Time, where initial frame = reference frame and time t = 0
	$r^{{}^{\prime }}$	Position of selected atoms in x frame, post superimposition on the reference frame, provided the frame x is captured at time tx
